Now, many of the early distributors did NOT even have a seal as these same distributors were used in other vehicles that had the distributor mounted vertically so any "dripping" oil would go back down the shaft and not be a problem. I believe Tim Engel has covered this topic earlier. Please use the "SEARCH" tab at the top of the JHPS forum to help in the future:
The shaft spins on 2 steel bushings and the seals I use to replace them need to have the upper steel bushing pressed down slightly. It is imperative that the top of the seal be BELOW the bottom "shelf" of the inner distributor, or the rubbing from the large thin metal washer above it will cause it to be ruined.
