The phone number for olson's gaskets is (360) 871-1207. They also have a website olsonsgaskets.com. I bought a set for my 52 4 cyl. 99 a couple years ago there. They are very pleasant to deal with, but they get plenty of $$$$ for the set. But, where do you find them? The only trouble I had was with the cork main seals on the ends of the oil pan. They were way too thick, and it was a nightmare getting the pan up there to get them to compress and stay put.
