Jay, is that the reverse light wire going through the hole above frame rail on this picture? There should not be any wires going through that hole, reverse light wires goes out through holes towards the back bottom of trunk drop off.

Looking good there Mike.  I coated the interior of mine with black rattle can truckbed liner.  Stuff is as hard as nails and has a nice mottled finish to hide a lot of the metal unevenness.  YMMV…

From up over the left wheel:
left tail light:


 
gas gauge routing:

 
note I have spliced in a gas gauge calibration device here.  It’s in the 3d printed box I made for it there. It’s held down by one of the tank bolts. The wood is there to kind of even up the floor for the vinyl

 
this is the running of the tail light harness from the left side headed over to the right side.

Hope these help some!!
 

If the clip is in correct it locks into the molding  ,the spring is a preload to keep the clip in place while tightening ,i sometimes bend the spring to keep it a bit tighter if the clip feels to loose in the molding ,now when tightening the clip is turning into the channel at top and bottom and shouldnt be able to come out 

Cleaned out the trunk from when we moved the Mustang to Virginia & started to work on the wiring in the trunk.
@JayEstes your Coupe looks great.

@JayEstes Love the GT style stripe.  Beautiful car.

Had a surprising weekend with my stang 'Penny' guys.  I had signed up for the Keels & Wheels "Concourse de' Elegance" show in Seabrook, TX.  Ive been twice before (last before covid), but this show is full of amazing vehicles, and I have been happy they let me even show.  
Well, I wanted to see if there was anything I could do to "up my game" in a short amount of time, and I noticed that the trunk was 10pts of the score.  I've never liked the stock treatment and said I wouldn't do it, but I never seem to get around to "doing it right" like I said I would.  So, to try to improve my score I bought the stock trunk liner, jack bag, and spare-tire cover.  Spent a little bit of time laying it in there, and trying to make it look decent.  Came out like this:

All I had to say was: "Well, it certainly looks better than nothing/what I had".  So I went with it.

The surprise came when I checked the judges sheet Sunday afternoon:  "Best in Class"!!  Unbelievable!
I've only put the car in maybe a half-dozen shows, and I've never done better than second place anywhere.  But the real surprise is that the show in Seabrook is one of the more prestigious shows (at least around here).  
It rained on Saturday, but didn't take any sunshine out of the day for me.  Aaron Shelby was here, and gave me a big "congrats" when I left the show - certainly an amazing day for me:

Damn, that's the first correct answer out of the last 8,439 responses!  I'm slipping, I tell ya...

Try unbolting the master cylinder & pull it forward a little & make the back seal in the master cylinder is not leaking fluid into the brake booster. I have had this happen to me & it drove me nuts until I found it.

Are your rear drums adjusted?  If there's a lot of space between the pads and drum, your brake pedal will feel much as you described.
The brake fluid must be going somewhere without affecting the braking ability.

Thanks ridge. I ended up installing without painting it. It was shiny aluminum after stripping the paint but I think the anodizing stayed on. 

Mine was cracked and it wasn't all obvious it was until I tried to pull it out of the booster, and it broke.  Make sure you get the right size hoses to go with it.  It should go from the booster into the main vac port on the back/top of the engine.  This hose is very important to overall vacuum, as it is a larger size, and leaks have a big effect.  It won't cost you but a little more to get the hose replaced.

The first thing I would check is the check valve where the rubber hose connects to booster. Also I had a vacuum booster once that leaked around the push rod shaft (the one between the booster and M/C} that caused the booster to function erratically sometime it sealed off and other times when you pushed the petal and released it wouldn't .

1 1/8in sway bar upgrade on the front is absolutely the best handling/safety upgrade I have made tot he car.  very little body roll for normal driving, much better handling
