1973 Duster with make over

I straightened the rear this weekend. It was about 3/16 off on each side just from welding the brackets on. I assembled it with the stock parts just to get my car rolling again. It will need new carrier bearings before i actually start driving it, but no sense in wasting the money yet. Also for how much power I plan to run, well i havent decided but no more than 500 hp. Next on the list it to build a welding cart for my new welder on the way. When I get that I need to finish welding my frame and coilover mounts in. Then prime the frame and get to installing the floor pans and wheel tubs. I am also going to order a roll cage, but im not sure on which one to order.
