Well I might have to eat crow, went back into all my old DC books to double check and the original book said same pump other than black spring. I’ll check my buddies 67 GTX this week to see what it has (original as built). I just remember taking the big pump (all orange) off a blown up 68 Hemi that I picked up to install on my max wedge (in 1974). Won’t be the first time Ive been wrong.
