HELP! Flexplate
I'm going to have to order a flexplate for my 65/389 and I am wondering if anyone has a good part number.
The transmission is going to be the 200-4R, do I need to order one to fit that torque converter or will any of the Pontiac fp's work? I can't find the one I had with the Turbo 400 that was on the motor and I don't know how many teeth it should have.

not sure about a 200R4 but the 700R4 i had installed used the smaller TH350 torque convertor bolt pattern on the flywheel.

2004R also uses the 350 holes.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
