Air shocks get a bad rap... and probably for good reason in Mopar circles. They work just fine in most cases but Mopars just don't have upper shock mounts strong enough to handle the extra stress. Especially when the metal is 50+ years old.

I'm building a 426 Street Wedge recreation and back in the day the owner would have used air shocks or shocks with helper springs to get the stance he wanted. To solve this weakness problem, I added a piece of 2"x 2"x .120 wall square tubing as an integrated crossmember to supplement the stock shock mounts. Admittedly it would have been a difficult job if the car hadn't been on a rotisserie. Bottom line: this will add enough strength to the mounts that I won't have to worry about ripping them out with air shocks.
