I put a late M40 in a car that apparently had an early one in it. The difference that is stopping the swap is the output flange, which is slightly larger than the original. I pulled out the flanges to swap them, but the later model output shaft has way more teeth than the early one so that won't work.

Does anyone know if any of the later model M40s had a smaller diameter output flange?

I really didn't want to spend any money on this swap, so otherwise... I'm going to shoot it. No, no - It just means it'll be off the road for a while until I find a replacement earlier M40 in the Bay Area.

Thanks,
