here's a pic... 2 flat tabs with captured nuts for the trim to attach to

 

or just Google this: 65 mustang fastback rear floor brackets

 

Thanks...I've been googling stuff all day and couldn't find the magic words. Yours did the trick.

Using those search words, I found a picture with some measurements in here...not sure it's right for a 65 though. At least it's a starting point.

I found the two brackets for the quarter trim panels...but those are the only ones I have.

I don't have the lower rear brackets or any of the ones for the rear trim that goes along the back (just under the window opening) or along the side. Also don't have the ones that are near the wheel wells.

Here's a picture of the inside of the car.

Some look easy enough to fabricate...I'd just need some measurements to bend up the metal.

I might just have to buy this bracket kit that I found online:
65-66 Mustang Fastback Body Bracket Kit, (Body Shell Part) - Restoration Performance Center

Anyone use this kit made by Dynacorn?

 

I'd buy that kit.

 

I bought the kit and there are no instructions or reference sheets that tell me where they all go.

I can figure most of them out (many are mounted in holes near the back window with screws). I don't know where the handle looking things go in the picture on the right.

Also don't really have any reference points or measurements for the stuff that get welded to the floor ( like the ones that the fold down seat mounts too)

Are the positions of these covered in any of the assembly manuals? I didn't see any reference pictures.

I looked through my Osborn assembly manuals and didn't see any dimensions given for the pieces that are spot welded.

I don't know what those "handles" are nor those 3 matching pieces on the left. I know they're not mounting brackets so they must be part of the unique fastback structure.

 

The 2 brackets that you say look like handles appear to me to be for a 67 fastback. They go above the wheels well just aft of the center of the wheel well. The 65-66 brackets look quite a bit different than those although the one in the kit you bought may work on a 65-66. They hold the back of the big fiberglass side quarter panel piece and the front of the small corner piece and they mount directly behind the beltline moldings. Take a look at this web page. It shows the kits for the 65 and the kit for the 67. The difference in the brackets in question can be seen in the two different pictures.

Even the link you posted shows the correct bracket for a 65-66. The picture you posted is for 67.

 

Thanks for helping me figure out what should have been obvious.

Here's the box they sent me:

Dynacorn is shipping the right set out to me and picking up the incorrect one.

Still trying to hunt down a resource to show me where to weld the lower pieces to the floor. I have a solution for the quarter trim panels. Just need a good location for the others that mount to the floor.

Anyone have a fastback with the interior gutted to take some measurements for me?

 

Thanks. I will call them on Monday to see why they sent me the wrong kit

Mine isn't gutted but most of the rear trim is out. What do you need?

 

A handful of pictures showing the brackets that the trim panels mount to would be great. There are a few different shaped brackets and I want to make sure I get them all in the right spots.

I might hit you up for some measurements for the L shaped bracket that the fold-down seatback mounts too. I don't know for sure if I need to use that to mount in a rear-seat delete shelf...posting that question in another thread.


Thanks so much.

 

Hello! I know this is an old post but im having the same issue, did you manage to get any measurements for those L shaped parts that sit under the seats that hold the interior plastic quarter panels? If you have other photos and measurements would be great help too

 

I can get you a picture of where I put mine, but they may not be perfect. To mount mine, I attached the lower bracket to the panel and then mounted the panel to the car (using the other mounting points). When it looked like it was in a good spot, I marked with a sharpie where the bracket met the floor. Then took the panel out and used my marks to spot weld it in place.

 

Hope this helps a little. I have more pictures of the trim brackets, but none when I reinstalled them.

 

Here is a picture of the brackets I think you’re asking about. The inside edge is 7”.

 

Thank you! Appreciate it!

I have these left over, any idea where they go?

I think 67 & 68 had two-fold down seat latches. So, if I had to guess the two with the holes may be used for that. Do have all the brackets for the trim that goes across the roof? Some may be used for that. Can you post a picture of what you installed?
