Having trouble with the oil filter on a 61 scout. The gasket that is to go in the groove on the top plate where the canister fits , will not fit. It is a wix filter #51156 . Any thoughts on how to get it in there, its just a little too thick to fit. Will soaking the gasket in solvent maybe shrink it a bit so it can be forced into the groove. This groove is barely big enough to fit the top of the canister itself.
