It's looking like I'm going to have some time on my hands so why not install some torque boxes on my 65 hardtop autocross car. The car is original and rust free and from what I have gathered the 2 piece versions are the way to go because you can reverse a flange and save having to cut into your existing floor. Unfortunately I have lost all of those bookmarks in the VMF site sale and am going from memory. I'm coming up with TORQUE BOX, LH, 67-68 MUSTANG COUGAR COUPE / FASTBACK - 3021-516-671L and TORQUE BOX, RH, 67-70 MUSTANG COUGAR COUPE / FASTBACK - 3021-516-671R. It seems Goodmark and Spectra Premium are one and the same? I'm looking to get something shipped quickly and the Goodmark site doesn't seem to be very promising in that regard.
