I am currently building a Challenger for a customer in a pro touring style. I have widened the wheel tubs 2 inches in the rear to fit a big back tire in it. Ordered a Hotchkiss TVS for it. The rear springs will be moved inside the frame rails to get maximum tire in the back. One thing I have wanted to do is box the LCA's. Any pictures of that? I don't want to block access to any important areas on them. I will also be bracing and fully welding the stock K member. This is a great thread chock full of info!
