I'm trying to figure out the differences between the supercharger snout seals. I've seen posted on the forums here the part # 7965 but I've also seen 7966, 7967 & 7968 for the Eaton superchargers. What’* the difference between the seals? As far as I can tell they are all the same size. Also, does the same seal work for the M62 and the M90 and the new M112?

Check out the calling all sc rebuilders thread at the top of the forced induction forum.

The only difference is the material they're made of. Viton is preferred for a rebuild.
