Differnt fly wheel for a TH400?

[Captainfab]

Ron pretty well summed it up.....sounds like you will need a flexplate. More than likely a 168 tooth one. Get one with the same tooth count as the flywheel that is on it now so you don't need to get another starter. Plus when you do need a starter you just need to ask for one for a '70 Chevy C10

I believe the smaller tooth uses the straight across bolt holes starter mount and the larger tooth uses the offset mounting. I know this was discussed on another thread but I can't remember which one.
