Im ready to order some Rear frame rails for my new project. I already have a comp. engineering 4 link Who makes the best fitting frame rails for a 63 b body? I have a JD squared tube bender and thought about making frame rails myself out of round tube. Has anybody done that? If so do you have any pics? thanks Seth

if you have a bender, I would do them myself. Morrison and Alston have more than doubled their frame prices over the last few years.
The ones that Summit sells are Comp Engineering I believe, they may work for you and are half the price..
The difference in the rails is from the hump over the axle backwards to where they meet the rear bumper panel...
