So I got my flywheel in that I needed for my 261 swap. When measuring across the clutch surface, I am measuring 10 7/8". Interestingly, I've found that the clutch from 42-46 had the same casting number for the regular flywheel and the heavy duty flywheel.

1. Will this require the 10 3/4" clutch discs? I'm about 95% sure it will but I want to be sure since theyre expensive. Jim Carter has new 10 3/4" ones but I haven't found them anywhere else. Everywhere else has 9 1/8, 10, and 11.

2. How hard is it to find 9 bolt pressure plates? I'm understood that they can't be had new.
