Made from steel this plate is many many times harder than the aluminum oil filter adaptor surface that the oil pump gears ride on. This plate offers the best matched ports of any gasket and also comes with both gaskets needed for assembly. You can even re-use your original bolts and these gaskets go in dry. Fits AMC V8 67-91, fits between oil filter adaptor and timing cover and now comes with two .0085 gaskets!
