I'm getting ready to overhaul the complete parking brake system on my '71 GS. Even replacing the broken foot brake assembly next to the driver's kick panel. I have this assembly but need all the cables, clips and small parts going all the way back to the drum rear brakes. Where is the best place to buy everything I need in a kit? Also, I've seen part numbers that are different for Turbo 400 vs Turbo 350 trannys. My set-up is a 455 motor with 400 tranny but, I think the tranny cross member is from a 350. Does this make a difference?
