Good part but it doesn't come with the rubber seal for the back of the oil pan
From Milwaukee, WI
All three seals seem to be good durable pieces, I like how the seal comes with extra rubber coating to ensure that it won't leak. The seals came in a very nice durable little box so that they wouldn't get destroyed in transportation which shows care by the manufacturer, it is easy to install this kit when the engine is out of the vehicle, I am installing it into my Camaro so I will find out soon how well it performs. It seems like a decent product though. I have never ran into any issues using Felpro products.

This rear main seal is a direct replacement for the factory seals which become brittle and leak over time. They are a perfect fit but require removal of either the engine or the transmission as well as the oil pan for proper installation. I recommend going ahead and purchasing the front main seal, oil pan gasket and valve cover gasket because chances are if your rear main seal has begun to leak then the other seals and gaskets most likely aren't far behind.

too thick for buick 70 455. crank locked up . try to turn and spund the seal apart.
Bottom Line not recommended
To large/thick for a 1966 Olds 425 engine. It was at least 3 times the thickness of the old one and would not fit correctly. I went with the rubber ones that cost twice as much but they fit correctly and were installed in minutes.
