Post strengthening frame

Hey guys,

Like I said in a post before I just recently purchased an 81 Mustang LX. It has t-tops and I'm a little concerned about the body getting twisted. When I bought it, it had a 5.0 in it, but it also came with a 347 stroker that was just rebuilt. I was planning on putting the 347 in once I upgrade the rearend and transmission. Is there any type of supports I can add to the frame so it won't get twisted with the new engine? any replies would be much appreciated

At the least, it will need subframe connectors. FORD also had reinforcement kits for the FOX MUSTANG convertibles (out of production) to tighten the body. The FOX convertible also used braces from the core support to the engine crossmember and then to the toe pan (out of production).

I have the illustrations and the kits could be easily duplicated...in fact, you could most likely do a better job than FORD did.

Also, you will want to reinforce the trunk pan/rear floorboard area that the rear upper control arms mount to. There is also a kit to reinforce the floorboard where the seat bolts down as these are subject to stress cracking. They were released for police packages.

Extra bracing from the cowl to the strut towers and you will have a regular road racer.

CAUTION! You know you have a true race car that when on hard launch spits it's windshield onto the track.

Thank you very much for the reply, I was planning on getting the subframe connector as you mentioned. If you could pm or email me the illustration you are talking about that would be great. Im not real sure what all the engine is capable of since ive only heard it start up. The whole ttops thing is what I was worried about.


Thanks again

Talking 89 Mustang seat reinforcements

Hello,
Can anybody tell me where to get the seat reinforcements (they came on police interceptors and go where the seat bolts to the floor pan) for a 89 Mustang GT? I found one place but they are no longer in business. Any help will be appreciated.
Thanks

Thanks, But I already have everything to stiffen the body except . a seat base reinforcement kit. The floor pan where my seat bolts to has ripped almost completely out due to good hooks and hard launches. B&C Mustang performance had them listed for 34.95 a piece, but are no longer in business. Any help in getting just the seat reinforcement kit will be appreciated
Thanks

Kenny Brown subframe connectors incorporate a seat brace. The pre-84 Fox Mustangs are famous for trying to drop the driver in the road. A friend of mine had an '83 2.3 (base engine) and his floor under the seat had to be welded.

Thanks,
The sub-frame connectors I have, do have the cross bar that bolts to the back 2 bolts of the seat (and are welded in).What I'm looking for is a plate that came out on Police Interceptors and bolts and/or welds to the seat base INSIDE of the car under the seat. If no one knows where to purchase these plates, I guess I'll have to make some or weld something to the floor.
Thanks

This looks like the place. I'll give them a ring and see what they have.
Thanks again
