Tube Rear framerails

I have a 72 Challenger and rear rails are bad. I would like to put some 2x3 tubed rails in and narrow my rear axle. Where is a good place to purchase some prefabed rails? Thanks Chilly

might check with Art Morrison

Your idea is good but not doable without redoing the rear sheet metal and wheel tubs.. There are not any tube rails made to replicate the factory rails..

I'm replacing all rear sheet metal. Frame rails need to be replaced do to rot. A friend suggested to check into tubed rails, as I had planned on relocating springs anyway.

Morrisons are pretty pricy.. Check out Alston Chassisworks...
