Can anyone speak from experience regarding the fitment of either Auto Rust Tecnicians or US Car Tool torque boxes?
Not interested in correctness. Looking for strength and good fitment.
Torque boxes have got to help and subframe connectors should be a bigger improvement. You guys that installed them, did you see a big difference and describe the difference if you would. ThanksI've installed the US Cartool torque boxes on both my Duster and my '71 Dart. They fit both cars very well. A little tweaking is need if you have subframe connectors to get the rears up against the floor because the boxes will likely overlap the connectors some, but at least on my cars it wasn't a big deal. As with all the other USCT parts I've installed they're very well made and strong, the fitting necessary is pretty minor, some fitting is going to be needed with any aftermarket body part.

Dunno yet. Cars not done. But i am sure they help a lot.Torque boxes have got to help and subframe connectors should be a bigger improvement. You guys that installed them, did you see a big difference and describe the difference if you would. Thanks
That's slick Matt.Ran my parking brake cable inboard of the subframe connector as well. This way its a straight shot to the back, and the cable and subframe connector wont interfere with one another.
First pic if from the front facing back. Its a 3/4" hole. The second pic from the back, the hole is only large enough so the parking brake cable circular retainer clip can fit and retain the cable. I used a 6" long drill bit to run a pilot hole all the way thru the crossmember so both sides line up. I mocked this up with my zee bar and speedometer cable. There is enough clearance to reroute it this way.
At the time of the pix being taken i had only pinned the subframe connectors in place.

I have auto rust techs full rear frame rails trunk floor with extensions front & rear torque boxes and their sub frame connectors all installed by them as they are not too far away. Cant really speak about ride performance because the car used to be a slant 6 and still not completely finished with a 360. But these are mopar guys and that is their main product the owner gave us a tour of the shop where they make all this stuff and it is quite impressive. Highly recommend their products. Keep in mind my car is about 200 pounds heavier with a bunch of dynamat and they did two coats of 3m undercoating which affects leaf springs as I have just posted a question about ride height.Can anyone speak from experience regarding the fitment of either Auto Rust Tecnicians or US Car Tool torque boxes?
Thanks for the offer. I placed the order already.I have a set locally if you want to see how they fit. Also there is a company that does full length rails for the abody, but its an involved process. I am also going with the frame caps for my 70 which has extensive rust issues.
Good choice! you wont be disappointed with those frame rails they are heavy duty.Thanks for the feedback. I've got the Dart torn down due to some rust at the firewall extension. 20 track days haven't been kind to the unibody either. I already have subframe connectors, Xv rad brace I made way back. I' m installing Auto Rust frame caps from the rad all the way back to increase stiffness along with some xv inner fender braces.
I have cracks at the firewall, inner fender and both frame rails on the bottom and an upper arm mount starting to tear from the inner fender...
SOP - Not really. I think it depends on the car, and also that these are incremental improvements. The way to tell for sure would be paved oval lap times, or for the 1/4 mile folks, 60' and 1/8 times on slicks. For launching like that it should also reduce wrinkling of the quarter panels...Torque boxes have got to help and subframe connectors should be a bigger improvement.

Sounds like a reasonable plan. Sorry a bit late, but I used ART's boxes as well. At the time, all that was available. You'll have to tweak for fitting.I'm not sure how, but I received everything from Auto Rust Tech in one day...
Besides the repairs, the goal is chassis stiffening. The Auto Rust caps will reinforce the frame rails from the rad support to the front floors. I will double the amount of spot welds at any inner structure I can reach, add inner fender braces as well as tie the upper control arm mounts to the inner fenders.
