Here is my fix for the rubber rear seal leak problem. Second pic shows how I attach the pick-up tube so it doesn't fall out.
I buy a sheet of cork gasket material and cut it precisely to fit with a razor knife. Never had one drop of oil get past this set-up. The factory rubber seals can and will leak or slip out on you. The wide custom fit cork seal isn't going anyplace.
Never tried the one piece pan seal, but probably well worth the investment over the factory set-up for the later pans that used the "tit" type rubber rear pan seals......Cliff
