Passenger Side 1-Piece Torque Box for 1965-1970 Mustang Coupes and Fastbacks.An old or weak torque box can mean body flex or frame twisting which can do serious damage to your Mustang. If you need to replace the entire torque box, we recommend this one-piece style reproduction. Made from high-quality 14-gauge steel.
*Will fit 71-73 Mustangs with some modifications.
My intention was to split the box apart and weld them in as separate pieces. As with any product, I had to trim, fit, trim again and fit some more but that's the nature of the beast when working on a 48 year old car. After I had the toe board piece fitting the way I wanted, I spray-bombed it for rust protection since the piece does mate face-to-face with the toe board. After I welded it in, I gave the exposed side a shot of paint too. I painted the inside of the second piece to prevent rust and welded it in to the reinforcement panel. Overall, it's a time consuming job but well worth the effort. I posted a YouTube video of the install. Search for '65 Mustang Restoration Part 5.5 Torque box installation'. I made a succession of videos in order to cover the entire install. Build quality: The metal used for this piece is thick and very robust. The box is a quality piece for the money if you plan on installing as I outlined above. Very satisfied.

By Bill Tumas: We're here with a replacement front torque box for your 64-1970 Mustang Coupe or Fastback. Ford realized the benefit of the front torque boxes in convertibles and use them since 1965. By 1967, they had a driver side torque box in the Mustang, by 1968 all three body styles benefited from both front torque boxes. Even though your 65-66 Coupe never came factory with torque boxes, we strongly suggest adding them to your restoration to increase the strength of your front end. Our torque boxes are made of heavy gauge steel and they come pre-welded so they're ready to install. Here you can see the torque box installed on this 1965 Mustang Coupe; it's going to weld between your frame rail and your rocker to increase the strength of the front end of your car. Whether or not your Mustang came with torque boxes from the factory, when you're doing your restoration, we highly suggest adding a set to your build.
