3 SPD shifter mounting

I think I got that wrong. The lower ring did not have a seal on it except for the Inland shifters,IIRC. The Hursts did not have a weather seal.
Oh I remember now; The boot had a metal ring on it that you slipped under the carpet and secured it with the 4 screws, and that sealed the tunnel. Then the trim ring just held the carpet down and in place.
Sorry I screwed up.Sux getting older.....i
