That cable is only used on Regal and Cutlass with the 200-4R trans. Chevy and GP are different. And THM200/350 are different. Stupid question? Why go used when you can still buy a new one from a vendor or a GM dealer. It could be kind of hard finding that exact cable in the boneyard.
Looks like its 4 different cables.
Buick and Olds are Regal and Cutlass
Chevy and Pontiac are MC,ElCamino,Malibu,RWD Bonneville,LeMans and GP
B-0 200-4R 25537476
B-O 200/250/350 22500579
C-P 200-4R 10026082
C-P 200/250/350 22500581
From what I can tell the big difference is where the cable goes through the hole in the shifter and trans brackets. The area where those U-shaped clips hold it on. The B-O is bigger IIRC.
