    Modified stock UCA for more caster

    Did not need screw in ball joints. I am running 14 inch original steel wheels on the 69 and 15 inch steel Magnums on the 70, so I have plenty of clearance between wheel and ball joint. Also, after the mod, I trimmed the outboard edge of the UCA which gave me 1/4 to 1/2 inches more clearance. When I installed the modified UCAs on the 70, first set the caster to 9-10 degrees; then after a few weeks reduced it a little. It corners nice. Straight driving is also improved, wanders a lot less. If/when I get rid of the factory PS, it should not wander at all.

    Modified stock UCA for more caster

    In a post I had mentioned that I modified my UCAs for more caster and a few members asked me how I did that. I was doing it on my 69 Grande recently and below are some pictures showing the modification. Moved the ball joint mounting holes 20 mm aft. If my memory serves me right, when I had done the math to get +4 caster and ended up with 20 mm. May be someone can do the math using stock spindle geometry and verify that moving upper ball joint 20 mm increases the caster +4. So, moving the ball joint holes 20 mm aft. Used a card board to trace the original holes and big hole for ball joint, then moved them 20 mm on the card board. Then made a template from the card board and made the steel doubler that is welded to the surface the ball joint is attached. The doubler was a piece of scrap sheet I had that was the same thickness as the UCA metal. Drilled the original and new (moved) ball joint mounting holes on the doubler. Used the original holes to attach the doubler to the UCA using bolts and nuts. had to slice the aft side of the UCA so the doubler will slide in. Welded the doubler and drilled the moved holes to UCA using the holes on the doubler. Had to cut the egg shaped top part and move that to rear so ball joint will fit. Need to trim some areas so ball joint grease fitting fits and is accessible.Then welded and braced everything. Had done this mod on my 70 Grande a few years ago on a 3 bolt ball joint UCA. 3 bolt UCA is a little less work to modify. As far as I remember, I have +6 or +7 caster on my 70 Grande with stock strud rods and stock LCA.

    Home Shop Air System upgrades - help

    I used a kit like that (don't remember the brand). Later on it started slow leaks at some of the connections. Now I have to turn the valve at the exit of the tank if I am not using air otherwise the compressor keeps coming on because of the slow leaks.

    1970 Mustang Exterior Lights (turn signals)

    Bob, someone took the time and colored the schematics from the CDs you buy currently. That schematic is not 100 % correct (not related to coloring), but very close. 70 should be close to 69 except the front turn signal and side marker wiring. If you post your problems, there are some electrical savy people here, they might be able to help.

    Photo needed of installed 69 Fender Extension

    Both front and back of the inner light area is originally black on my car. The tab that the grill mounts to is also black. The area between inner and outer lights on the inner light side is body color over spray but chrome trim covers it.
  6. Original wires on my 69 is not encased in plastic conduit under the door will, they are braided. I don't remember plastic conduit on my 70 either. To me, plastic conduit means someone has done wiring repair.
  7. The aftermarket switches especially the canceling cam part is garbage. I am working on modeling the canceling cam (slowly) so I can 3D print it. I am thinking that I will have to modify the model to make it flexible enough but still work and last using the available 3D filaments.

    Console lid dimensions please.

    Now, if you were so kind, you would have modeled it and sent us the STL files so we could 3D print it :)

    69 front valance same as 1970?

    Yes, my originals are like fvike's photo.

    69 front valance same as 1970?

    Towards the front, the light bucket sticks out on my 69 with original valance and fenders.

    By the way, I used LVLP spray gun.

    Home Shop Air System upgrades - help

    I went through this last summer before I painted one of my cars. Was going to use a home AC evoparator as aftercooler. One tip; add a second check valve (the valve you have at the entrance to the tank) to the entrance of your aftercooler. That way when the compressor stops (when the pressure reaches to set point) the air in the aftercooler won't be released making a looong hissing sound. I have not installed the after cooler though, just made a Z shape using copper pipe (about 40 feet total pipe), air from comp goes in at the top and the lines are inclined down so the water flows down. Then attached the water separator/regulator to that. Drained the water from the tank and water separator before paint, added the disposable filter (bought from paint supply store) to the gun and painted the car. Did not have any water problems in paint on a humid September day in GA (besides the humidity leaking from the mask and my sweat running down like a stream). I don't think I will add the aftercooler; I believe the Z cooler is effective for a hobbyist unless you are a body shop painting all day long.

    Fastback inner rockers

    You do not need a model, FEA etc to show the effect of SFC. Just glue 2 pencils to the edges of an 8.5x11 inches card board like rocker panels. Twist it from opposite corners and observe how much force is required.. Then glue 2 more towards the middle like SFCs, then twist again. Then remove the 2 pencils in the middle and glue them in an x pattern like tying right front rocker to left rear, and left front to right rear; twist again. Here is your rudimentary test without using expensive resources.

    Fastback inner rockers

    If I understood your post right, you said they tested a Mopar and added boxed front radiator support like Mustang (and some other stuff). I do not know what the structural differences and resemblances between the Mustang and Mopar, but if they added boxed front radiator support lke the Mustang has, there must be differences. So, that test does not tell me anything about a 69 or 70 Mustang. It only tells me which additions stiffened that Mopar they tested. If those mods worked for that Mopar, it does not mean those same mods will work the same for a Mustang because structurally they are not the same. If we follow those tests and add everything they added to the Mopar, we have to add a second boxed radiator support to the Mustang. May be one day some manufacturer with resources will test a Mustang on a test jig and show us how their SFCs that only tie front rails to rears increased (or didn't) the rigidity of the Mustang.

    Fastback inner rockers

    Try jacking of up the rear tire. Use the factory jack point on the rocker or the area just front of the leaf spring attach point and let's what happens. You can see where the lift pad is on my car in one of the pictures I posted.

    69-70 Hood catch

    To me, it looks like both ends are welded to the round piece in the middle.

    Did you see the car latoracing posted on this tread? Looks real stiff. I think that car may bounce like a pinball in a crash if it hits something very heavy.

    Well, on a head on collusion the energy that will go to the rear structure has to pass through the cabin right? People sitting in the cabin will be subject to that. You want the energy absorbed before it reaches the passenger.

    Fastback inner rockers

    Coupe rear seat area structure on a fastback is not feasible in my opinion, coupe has a lot of structure like the shelf etc which carry load. I think cross brace under the car like TCP X-brace and export brace are best bang for the buck with little cost in time and money.

    Fastback inner rockers

    If a part is not bending and deforming, it is just tranfering the energy, not absorbing it.

    Fastback inner rockers

    I would prefer to be in an accident with a car without SFCs so the floor, rockers etc will bend and absorb energy instead of my body absorbing that energy. Anything that bends during a crash is absorbing energy that will otherwise be transfered to occupants. Put a brace like the coupe has behind the rear seat and increase the torsional stiffness of the fastback.

    Fastback inner rockers

    You do not have to do it for me. I have been an aeronautical engineer designing aircraft structures for a long time (30 years). But I went to the shop and did something for you. Subject car is a 1969 Grande, all original sheet metal except replacement left door skin. No modifications to body and structure, not even extra welding. It has an export brace but I loosen the shock tower bolts that hold the export brace so the body can move anyway it wants. No rear glass, no seats and door and rear quarter interior panels. No fuel in the tank and no exhaust pipes after the mufflers . See pictures of right front, right rear and left rear tires;, only left front wheel touching the ground.

    Fastback inner rockers

    Yes. Remember what I said in one of my previous posts; "strategically placed tie between right and left rocker decreases twist". Fvike tied the right front rail to right rear rail with welded SFCs, the front rail is already tied to front torque box which is tied to front rocker, same for the rear. Then the X-brace tied the SFCs to each other (right front to left front, right rear to left rear), so in doing that he tied the right rocker to left rocker both at front and rear and did what I said is required.

    Speedometer Headache

    Can you post the contact info for the speedometer cable manufacturer you used? It may be useful for folks who needs a new cable.

    Fastback inner rockers

    Can you jack your car up without the X-brace with just SCFs that connect only right front frame rail to right rear and left front to left rear frame rail and see if you can lift all 3 wheels?
