mine is a 12A, and i wanted to use studs, but at the time we couldn't get em short enough, the 20mm between a 13B kind of matters if you want to use a flywheel...

so anyways i just used stock 12A bolts and did the RB silicon thing.

the problem with stock bolts is that they hit a resonance in the 9K range, the factory fix is a bit of rubber in the middle, so the RB silicon should work just as well. no resonance = no problem
