I want to put subframe connectors in The Charger and want to get a few opinions on my options. I've made and welded them in 2 A body cars using 3x3 .120 wall tubing. I cut them to the contours of the floorpan and then REboxed the sections where they were cut away. The Charger front frame rails run at an angle towards the torsion bar crossmember, so I plan to simply run the connectors in a straight line from the rear frame rails forward as I have seen elsewhere. The rear frame rails appear to be 2 1/2" wide, so the 3x3 tubing may also work here. I have seen some ads with connectors that are "Laser Cut" to match the floorpan, but it seems to me that there is probably more stiffness with a boxed connector rather than a 3 sided one.
Opinions?
