1967 Dynacorn Fastback

Rusty Gillis
In this build I will show the good and bad features of building a Dynacorn body.

My customer has wanted a Fastback Mustang for a long time but could not find a good body that did not require a lot of rust repair so he decided to buy a 1967 Dynacorn body. He started calling around and could not find a body back in January. He called Dynacorn and they told him they had no idea when they would get one in. He was getting discouraged and had to go back to work where he works 10 weeks and than is off 10 weeks. When he got back in town he started checking around and still nobody had one. He found a project that was never started that came with a lot of extra parts so he bought it.

Some of the good points are the shock tower braces, extra welding in the engine compartment and a lot more spot welds and the export brace

Another good feature is the one piece seat riser.

I have never seen an after market valance fit this good but it is bolted together instead of screws.

I've always wondered about the quality of thos Dynacorn shells. Keep us posted as the build progresses.
 
Rusty, this will be great to watch.

I know the Camaro body was great but all the gaps needed work, also on all of them (4) the rear tail panel was faster and cheaper time wise, to cut out and weld or bond in a new one.

STILL!!! Nothing is better then working with good sheet metal!
 
We have not had the time to work on this yet but have an issue with the door gaps. This is what we found so far:

The hood bumper brackets are not straight

Dynacorn does not spot weld the quarters they are plug welded and than they ground the welds to much.

The door and trunk bolts are metric

We thought at first they had metric threads but they are the same as all Mustangs so I changed them. Notice there is no ecoat under the fender brace. We will be sanding the complete body and spraying 2 coats of SPI epoxy.

I have always wanted to do a dynacorn, but not because I thought they were perfect, just be neat to do one and not have to worry about rust, but as rusty is doing, you need to start from the bottom even with a new body, nothing is perfect. I always wanted someone to bring one in to do a pro-touring theme, would have to go through the whole thing anyways then.
 
Rusty, will this be titled as a 1967 Mustang or a 2012 custom built vehicle?
 
Installing the TCP subframe connectors. The minimum clearance between the factory frame rail where the subframe connectors attach in the front is 27 1/8" the Dynacorn body was 27 1/2" so were were okay.

Once we had them welded in place we went to test fit the center brace and it would not fit in the back. Dynacorn welded the frame rails in the wrong place. The distance between the frame rails is 1/2" narrower than stock spec in the front and 1/4" in the rear behind the shackle mounts. We will have to modify the TCP center brace.
 
The snubber brackets are not mounted in the same place on the frame rail so Brian removed them so we could install the cradle for the TCP rear suspension.

Cradle bolted and welded in place

Wow. I have wanted to see one of these builds for a long time. I couldn't think of a better person to achieve this while pointing out and fixing the problem areas. My hats off to you Rusty. Thanks.

+1 :)
 
The cradle is supposed to bolt to the pinnon snubber mount but there was no holes and it was off center a little.

Brian welded a bracket

Brian decided to improving the welding a little

They welded the other side

The deck lid fit great but the doors, fenders and hood are another story.

Once the fender apron holes were modified to get the fender back so there was not a large gap at the windshield and front of the hood there was not enough gap at the door.

The hood is to wide at the back and will need to be trimmed

Ha, well at least the deck lid bolted up. Can't believe they didn't have it dialed in better since they make the body and the panels. You would think they'd have some sort of quality control that was better than the factory had 45 years ago.
