Just out of curiosity, did you have any issues with the new snap ring that came with your FPR? I just replaced my FPR for the second time and found that I had to keep using the "original" snap ring, both times. The one that came with the new ones was not only too small and wouldn't snap tight into place (with the S/C FPR block as well as the OEM FPR seat) but it was actually a different design altogether.
Anyways, just curious. Maybe I got the 2 flunkies that existed, heh.
Had the same experience when I changed mine last summer.
