Big Block Kickdown Linkage

70 and earlier 3 piece linkage is the same in A, B, C, E, bodies if it 3 piece. Most later models are one piece accept for A-bodies due to firewall clearance
That’s not quite true. Everything from the upper pivot arm to the pivot on the transmission is different on a big block A-body. I have the part numbers for those pieces somewhere since I had to find them for the M-code ‘cuda that I was restoring at the time.
