Oil filter block plate

the small red gasket is used with the 90 only from what I have researched. If you want to use it, you could use it on the outside of the plate to prevent galling of the nut against the plate. I just bought the nut ($3.48 from Oconee Off-road that is called out for a 91-11 Jeep Wrangler, 53007563AB) and it fits perfectly. Use the large gasket under the plate and it will lift the plate about 2mm off the bolt boss, and the nipple will cinch it down tight against the inlet. There is no gap so there is no oil bypass there. I had to give my plate a little tap to get some clearance there as my cut out 1/32 cork gasket is probably the wrong thickness.
