Early A-body 90 degree oil filter adapter issue
In my stash I have a pair of NOS direct connection ones, the box says P3690884, adapter inside has 3690743 stamped on i, other has P4532633. The end of plugs are different and the part where the oil filter spins on is slightly different along with a few other numbers that were stamped in them. Other than that they are the same, one has less casting flies. These angles slightly but box says “permits 90° rotation of oil filter”
