I've reached a major milestone today. I have this coupe kit in my garage for a bit over three years, and I've finally got to the point where I can take off the body.

What better time to start a build thread!

This video should explain why it took so long to get here ...


And here are a few pics to back it up ...

Enjoy!

BTW, it's Glenn ... guess I should update my sig. :)
Glenn, sorry about that. I knew that too, don’t know how Keith slipped in there.

PS. Watching my stuff for a long time, with the emphasis on long!!

That's looking nice. Pretty impressive modifications.

Keep us posted on the progress.
Thanks.

Today I finished up the firewall support frame. As I mentioned in the video, it will support the heater/ac unit, and probably some other under-hood and under-dash stuff. It’s the horizontal piece in the foreground.

I also did some design work on the changes to the rear framework. The plan I had for the forward fuel tank support was questionable. I can do something much more solid by building off the rear X tubes of the IRS cage. And adding the 2" square tube across the rear that I mentioned in the video is gonna get interesting.

I think I'll dive back into Seattle Dad's build thread for some research. ;-) Thanks, Michael!

Rear trunk wall mods iplace

Today a friend and I tackled the mods to the rear trunk wall. The lower 3/4" square tubing is replaced by 1" square tubing. It's re-positioned slightly for the rear fuel tank strap of my custom tank. There is also a hoop of 2" square tubing at bumper height to better protect the fuel tank.



More details here: https://flic.kr/s/aHsm9s5AaY

Today I welded some stringers in the trunk floor and added the mounts for my fuel tank.
The tail end of the car will be a lot stiffer, will give decent protection for the fuel tank, and will add about 3 cubic feet of space.

And thanks for the compliments, guys. I always appreciate a little friendly feedback.

I’m fighting my way out of that hole, Mark!

Frame Modifications

I'm making some serious progress on my frame modifications. And I'm immensely grateful for my friend Bob for his help. He's not just a fantastic welder, but he's a great sounding board for ideas and plans.

Probably the most anxious frame mod so far is cutting out the original solid rear differential mount in preparation to install my new mount with a bushing. It was kinda scary cutting it off ... sort of a "point of no return".

Here's a link to my Flickr album ... https://flic.kr/s/aHsm9s5AaY

Pass-throughs for undercar exhaust

One of my big "wants" for this build is under-car exhaust. I haven't seen anybody do this with a Coyote in a Gen 2 coupe, but I'm going to give it a go. A big item for pulling it off is to run pass-through tubes through the rear 4" round cross member. The Travelling Builder posted up pics of an approach to this a while back. I thought it made a lot of sense.

I did the grunt work while my friend Bob did the challenging stuff. I think it turned out very nicely. I'll attach a couple of pics here. More pics are in my Frame Mods album on Flickr that I mentioned in an earlier post.

Imitation is the sincerest form of flattery. Thanks, Mark!

That looks great. I wish you success. I so wanted to do undercar exhaust on my Gen3, but I gave up. There is just No room. I welded several mock-ups, I tried oval pipes to the side and then over the tires, but no way. There is no room in the transmission tunnel.

Lots of great work there Glenn! I’m going to have to follow this one more regularly! Everyone keeps stepping it up!!

Good luck with the rest of it.

Nicely done... looks like it will hold.. !! What are you going to do with the scallops in under the doors.. fit a cover or build them out so they look like they were never there..?

Great work! Your post is timely because it shows how much effort is required to put power windows in this car. That's how the total project hours can grow to twice what was expected, for a standard build.

Even though I've never built an FFR car, I have experience with putting power windows in a fiberglass car, where the doors have no provision for them. My '37 has one piece doors with hollow-framed window openings that made the job very challenging and took many hours of hard work.

Thanks! I know people who have built their car in less time than I have in these doors! And there are easier ways to do it. But in any case building the track and making the glass move is only the beginning of the work.

I wrestled the diff into place to prepare for the final frame mod. I’ll be installing a new rear diff bracket that uses a bushing.
I’ll be shooting for the diff to be nose up at 3 degrees.

Interesting... I hard mounted the front, am thinking it would be a better idea to put the rubber bushes back in now.. !

The frame mods are DONE!!!

I did a lot of prep work this week and man, did it ever pay off today!

First up was finish welding four jacking points that I fabricated using short lengths of 2" square tubing. The front ones are on the bottom of the round tubes at the front of the foot boxes. The others are on the bottom of the 2" square tubes at the rear of the cockpit. Thanks to Glen Sides Sr and Matt Sides for the idea (Sorry, no pictures of these).

Next up was finish welding the rear diff mount. I hoisted the diff into place and secured it with front mounts and supported it with a ratchet strap. Then I bolted everything up and tacked the mount to the frame. I pulled the diff out, and my friend finish welded the mount to the frame and added some serious gussets. That baby ain't going anywhere! (First pic).

The next item is something that I've had in mind for a long time. The roll cage tube that is just above the door is a real head banger! After some discussion I decided to do something about it. I settled on an X frame design. The front ends of the tubes do not extend to the corners of the front hoop, so it's probably not legal for any sanctioned racing. But I think it's perfectly fine for the way I'll use the car. This makes a HUGE difference in space for my head!
(Second pic)

Yeah, I'm pretty happy with it! (Third pic)

Finally, with the help of another friend and his box truck we transported the frame to the paint shop, it's new home for a while! (Fourth pic)

Good eye! I didn't look it over very closely. but I think they said it was a '70. It's at GCR's Auto Collision in Dalmatia PA. The shop came highly recommended. They have a number of Mustangs in the shop. One looks like its going to need new everything except the VIN tag! And there was a very cool early Corvette, too.
