A-Body Frame/Body Jig
I subscribe to that channel, lots of good info. I agree with Oldmanmopar on the support of the car, though. He fabbed a cool way of holding his car up and moving it around but for frame work, I think I'd prefer something a little more stationary and solid. He's actually repairing the exact same issue my car has, except since my frame rails were capped under the car, I'm suspicious about the condition of the rest of the rails. I got a really nice front clip from an Alabama car to splice onto my car.
