oil filter adaptor

Check out Ebay. The sellers are really nice and have pictures how they go on. Manici Racing has them cheaper at under $10 plus shipping.

Only thing is Mopar has that thick cork gasket and I seen some ebay sellers showing a thick plastic gasket for between the bolt and the block. The small thin gasket goes behind the bolt and we all know where the big gasket goes.

Which Adapter seals better thou, the cast iron or the Mopar aluminum one. I have both.
