Got to take it for a bouncy cruise without those rear shocks. The wheel spacers in the front seem to have solved the wheel-to-control arm issue. The c-notches solved the axle-to-frame issue. The engine seems pretty strong, the trans makes a lot of noise even for an SM420 and the clutch is hammered.
I also converted to a 66-up style parking brake setup. I just used the stock '65 cables that came with the rear end, a reproduction cable support rod and coupler kit, and made my own cable to join the two coming from the rear wheels. The cable kept stretching so I had to keep making it shorter, but I got it eventually. I actually used my MIG welder to zap the ends of the cables to hold the cable stops...soldering the cable stops was not working.
I decided to go with this rear shock setup. Made the new uppers tonight, the paint is drying and hopefully i can install tomorrow.
