There's only a few small details to button up on the interior now. Need to mount up the tach and finish the back seat, I have a chunk of carpet ordered for that. The main thing I'm dreading right now is re-installing the vent wing windows. I'll probably bite the bullet and mess with that tonight. Once those are in, door panels can be slapped back on.

Wiring is going to be waiting a couple weeks now. My buddies shop is full of cars that he's waiting on parts for (way too common of a complaint right now).

Great project! Great progress.  I won’t argue, wing windows are not my favorite.

Ready for wiring. Behind schedule (as usual), but still moving forward. Dropping it off tomorrow, hopefully he can knock it out in a couple weeks. I can't wait until the engine and trans are in the car and the front end sits down, then we'll see how it looks.

Made it to my friend Taylor's house for wiring. It's funny, the car is now parked in a shop full of Honda's. He was showing us some of the wiring harness patterns he has made for car types or engine types that he does frequently. The Mustang is a cakewalk compared to the all the data acquisition wiring he does on a modern turbocharged car. Excited to see his work when he's done.

Very nice Mike!  That thing is going to be so sweet  :D
A careful study of failure will yield the ingredients for success.

Coming along nicely! do you have any close ups of the new Centerline copies? I have had Centerline AutoDrags on several cars since the mid 70s, the same set of AutoDrags have been on my Fairmont drag car since the mid 80s. Funny how so many people like the old Modified Production look of the Fairmont, including the Centerlines and Harwood snorkle scoop, but they were actually "state of the art" at that time, and I never felt any need to update them.
Also, I know they are not really thick, but when it comes time to install the headers on your Mustang, I am sure that you will be glad that you don`t have real Cobra Jet reinforced shock towers to deal with. Every 1/4" of room helps in that department!

Rory, I don't have any real good pictures of the wheels, but I was able to take a higher quality photo and zoom in on the front wheel. These wheels were my uncles choice. He had been on ebay hunting for a set of autodrags but none of them were the proper size.

Funny you mention the shock tower reinforcement. On our black '67 we installed a shock tower reinforcement kit, this one doesn't have that. We have the same exact REF headers for both cars, this one is noticeably easier to install the headers on. When we mocked up the '67 we had to get the grinder out and clearance parts of the reinforcement plates.

Well we have power! Few things left to button up on the wiring and we'll have the car back! Getting more and more excited here

A little longer wheel stud will make the tech inspectors happier  ;D

Haha, yes or a shorter nut. These ones are 2-3 threads from sticking out, kind of annoying

Engine is ready to hit the dyno again this Thursday. Last time we had a dual plane intake on it that had been highly modified and worked OK-ish but was definitely holding it back. This time its a normal tunnel wedge style intake. Thursday we will test an un-touched intake manifold, Friday we will test one the my uncle Bob has modified a ton by widening the ports and installing these pretty crazy looking 3D printed air foils around the pushrod tubes.

We are still waiting on the transmission for the car. All wiring will be complete this week, and pending the engine dyno works out, the trans will be the final hurdle before we can have the car in one piece.

Love those dyno headers! Sure look great, EGT bungs too. What kit did you use? Most likely for a BBC then just used FE flanges? What diameter are they, and with a step? Did you weld them up or have someone build them?
