This product is not specific on roller pin size. There is two lengths for these clutches, 1" and 1"1/8, reminder that just because it's not the wide roller kit does not mean it will be the correct roller pin size nor button size. I had to get a set elsewhere to make the kit work. Other than that the other parts worked fine
There is everything there to do a complete clutch rebuild on the small blocks. Including the cover bushing. Then i send it to tru balance performance up in Idaho to get the clutch balance what a difference.
