Repairing Mustang Torque Boxes and Floor Transitions | Dustin’s 1970 Mustang Ep. 4 | ALLISON CUSTOMS

Nice detail of the internal mustang floor and learning about the Torque Boxes. :)

[@AllisonCustoms]

Thanks!

[@johnhalberstram1806]

Thanks for these videos, big help

[@AllisonCustoms]

Thanks for saying so! I’ll keep,them coming!

[@c3dk]

Super nice job !! Right now I'm looking at a very rusted 70 Mach 1 :- )

[@AllisonCustoms]

Thanks! I do get tired of rust. But at least with the Mustangs all the parts are repopped.

[@rcito1]

What did you guys spray it with to protect it? Sand it first then primer then the grey protectant? Thanks love the vids!

[@AllisonCustoms]

I like to use a high zinc weld thru primer and / or Rust-Oleum Rust Reformer 215215 - amzn.to/3q2gDkv

what are the holes in the top of the torque box for and arent they being covered up by that toe board? I know the one is for the e brake but its confusing because the ebrake lever is in the cab and this seems like it would route the cable into the engine bay?

[@AllisonCustoms]

To my knowledge the e brake cable is run completely under the car and then comes into the cabin (thru the firewall) very near the top of the pedal assembly. Here is a link I found that show the routing. www.concoursmustang.com/forum/index.php?topic=19118.0

@@AllisonCustoms thanks for the reply. I did more research and im pretty sure it doesnt enter the firewall. the torque box you saw has those two little holes top left, and then the channel exit just to the right of those. The channel runs inside the torque box with the entrance at the bottom. so the cable runs through there and so I would think you gotta cut a hole in the toe board for the cable to come up through that channel. the two extra holes im told are just relief holes whatever that means

[@AllisonCustoms]

When the owner gets ready to start back on that project, I’ll have to pull all my assembly manuals out and take a look. That car has been under a cover for about 18 months waiting on the owner. So, I honestly haven’t put a whole lot of thought into Mustangs in a while.

We’re did you get the table sir?

[@AllisonCustoms]

I made the jig about 5 years ago, to fit multiple body styles, with lots of adjustability.

[@hughphillips67Mustang]

What's the point of a torque box? Is it really needed if it's just a cruiser car? I bought my 67 mustang, and the previous owner took the torque box out. He got sick and passed away before replacing it. The car has all the body work done, and newly painted. Is it worth me doing all that work, and repainting the car if it's just a cruiser?

[@AllisonCustoms]

The rear torque boxes help transfer the lifting and twisting forces coming thru the leaf springs into the floor and (mostly) the rocker panels. The rocker panels are really the only “frame” the Mustang has. The front torque boxes also transfer the steering and other suspension forces into the rocker panels. The rockers are attempting to keep the car from twisting like a pretzel 🥨. So - Yes I would want them or something to take their place - like a full aftermarket chassis. Possibly some high quality subframe connectors would solve the issue as well. But most of those that I have seen get bolted or welded into the torque boxes, front and rear. Hope that helps.

[@hughphillips67Mustang]

@Allison Customs' - PROJECT CAR TV is it a safety hazard not to have them? I guess my nerves are just on end not knowing what I should do. I don't have the tools, the space, or the money to do this type of work. So, I guess that's why I'm questioning it.

[@67mustangcouperestoration]

@@hughphillips67Mustang the 65-66 Mustangs didn’t use torque boxes. Ford added one in 67, but only on the drivers side. From 68 onward, they had them on both sides. Could you live without it on a 67? Possibly, if you have a straight six or two barrel 289 (lower HP). If the rest of the sheet metal on the car is solid, you could probably get by, but if any of the firewall, lower cowl, floor, or rocker have rust, there is a good chance your car may start to sag/fold right where the torque boxes are normally located. That’s because it doesn’t take much strain (applied load) for the floor and firewall sheet metal that’s between the rockers and frame rails to flex/buckle/twist.

[@hughphillips67Mustang]

@67MustangCoupeRestoration yes I only have the 2 barrel 289. And from what I can tell, the exterior metal is all solid. The cowl around the top hat is bad. And the firewall looks thin in places. I will just get it done by someone that knows what to do. And has the tools and space to do it. I hope it don't cost me a kidney to have it done.

What he said!
