  1. Only war t know is to attempt to adjust it. Have all of the other componets been ruled out, tie rods, idler arm, sector shaft arm, etc?
  2. Before you cut anything out My recommendation would be to make a detailed diagram & note measurements as well as cross measurements. These measurements will help determine if the car is currently strait & square, or if adjustments need to be made. ASSUMING everything is where is should be they will help you get the new parts in the correct position. 69 & 70 are the same dimensions. Measurement "H", in the diagram below is correct, however, they are measuring from the incorrect hole, it should be the hole in front of the tunnel brace. I would also measure the distance between the top of the aprons in multiple identifiable locations, inside bend NOT the holes. Then cross measure from the firewall to the front of the apron.
  3. Long cables will add resistance and voltage drop between the battery and the starter. What is the voltage at the solenoid static and while cranking?
  4. Shave the gear in the end of the Speedo cable to one with more or less teeth depending in the direction it’s off. https://lmr.com/products/Mustang-Speedometer-Gear-Calculator?gclid=CjwKCAjwuIWHBhBDEiwACXQYsYo3gGmyCZL6IhOQtOUBnEqPIn2G4AFt8mjdBdUvFzkvxuw1PH-WDRoCB54QAvD_BwE
  5. You should have the builder of the trans validate. I know of no .78 option for an aod/4r70w/4r75e. As well the math does not support .78.
  6. I knew I had seen pictures of this car before. Are you sure you have the correct VIN? Ah, reading more closely I see the photo is not the same car. https://www.concoursmustang.com/forum/index.php?topic=15252.0 Mike
  7. 4r70w is a 0.70:1, assume that is a typographical error. It really depends on the tq available at the cruise rpm, the converter and the lockup schedule. My lightning cruises at 2200 rpm at 70 mile an hour, lots tq available. I believe I would have a discussion with to the cam designer about this. However, my guess the 3.70 or 3.50 will be fine. 3.00 may be fine as well but may require a different shift schedule specifically for it.
  8. Take a look at these: https://www.428cobrajet.org/speedo-gears https://www.428cobrajet.org/speedo-calc
  9. Brackets from here, rotors, and some new or rebuilt calipers and your your good to go. https://mustangsteve.com/product-category/rear-disc-brake-conversion-brackets/
  10. I would expect most any aftermarket 31 spline axle will take what you may throw at it with any street tire, they are not going to grip anyway. There are many calculators available online to help with gear selection or get out the old slide rule.: https://spicerparts.com/calculators/transmission-ratio-rpm-calculator
  11. If I recall correctly the vaccume line runs to a valve that closes when the engine warms up, cutting off vaccume to the motor. No or less vaccume allows the motor to open the door allowing ambiant air to enter the air cleaner. Door is normally open and closes with vaccume.
  12. Should be open normally. Closes in order to draw warm air when cold. These may be rebuilt, however, not sure it is worth the cost or effort.
  13. There is always the chisel & its friend the BFH to split the cap. :-)
  14. May be time to break out the dremel. I would not grind on the driveshaft only on the clip and or cup. Those retainers are meant for joints that have the grove on the inside portion of the cap, near the center of the cross.
  15. Rather than work from the ends you might try trying to get a pick or small screw driver between the clip and lip of the driveshaft and pry to the enter, up in your picture. With any luck it will force the two ends together and the clip will pop out. Also applying inward pressure on the cap may give you a bit more wiggle room, socket an vice or c clamp.

  17. Sounds you may have some bump steer post spri g install. Are the tirodz parallel to the ground?
  18. Watch a few of these videos to get an idea. Take lots of measurements. More than you think you need. https://youtube.com/channel/UCG-IsvXgmiBXavN03_C-PNA
  19. I suppose anything may be adapted. But if it were easy I think we would have a vendor selling the 71 up conversion already. The 71 up box mounts higher, frame rail and shock towers changes to accommodate this. Also the frame rails are further apart on a 71,72,73, thus more room for the box.
  20. Doors with no rust are hard to find. I have a pair I purchased several years ago about of Arizona and they too had some rust through on the outer skin. The shells are good and will be patched or new stains for my car. I'm originally from southeast Iowa, Blakesburg. Now reside barely north of Dallas, TX.
  21. I would be interested in the shift mechanism, inside and out, detent, shaft, nut, outside linkage, etc.. https://www.google.com/search?q=4r70w+shift+mechinisum&tbm=isch&ved=2ahUKEwiI08as_P7vAhXQf6wKHbfwDfAQ2-cCegQIABAC&oq=4r70w+shift+mechinisum&gs_lcp=ChJtb2JpbGUtZ3dzLXdpei1pbWcQAzIECCEQCjoECCMQJzoECAAQGDoCCAA6BggAEAgQHjoFCCEQqwI6BQgAEM0CUNcOWIN3YLR5aABwAHgAgAGpAogBlhiSAQYyMC43LjKYAQCgAQHAAQE&sclient=mobile-gws-wiz-img&ei=0IV3YIirAtD_sQW34beADw&bih=1280&biw=800&client=tablet-android-samsung&prmd=sivn#imgrc=9ZHgjPd3pW1GBM
  22. Classic tube made a set also, from stainless. From what I have seen in all of my searches these re out of stock as well. There was another post where someone posted a diagram but it did not include all dimensions & was for one bracket, do noo know if it was small or large.:
  23. You should be able to pickup a solid state regulator at any auto parts store. If you need it to look original you may order a new cover or use your old one. The another alternative are these solid state with new cover. Note the without ac is out of stock until April.: With AC: https://www.deadnutson.com/1968-4-1970-autolite-voltage-regulator-55-amp/ Without AC: https://www.deadnutson.com/1968-4-1970-autolite-voltage-regulator-38-42-amp/
  24. You may order a motorcraft from your local Ford dealer or just about any auto parts store. If all else fails there is ebay and rockauto. HTTPS://www.rockauto.com/en/catalog/ford,1969,mustang,7.0l+428cid+v8,1132434,electrical,starter+solenoid,4188
