I bought a partially restored '70 Road Runner on Ebay last October and am working on it every single day. I am retired It is a 440 4-speed and was a 383 car as it has an 8 3/4 rear end. I bought the Dana 60 that was shortened to 48" also on Ebay and am moving the rear spring mounts in to the frame and am installing new wheel tubs now. I am getting ready to do some welding as soon as I master MIG welding.
