Spin on oil filter adapter kit for MF 135. The Adapter Kit has 1 small, 1 large gaskets, 1 bolt, and 1 plate. The bolt has 2 different threaded sizes - one end goes thru the round plate and in the engine block the other end the oil filter. The round plate has 2 sides. One side has a 3 1/4 in. round raised circle with holes in the center which appears to fit the rubber ring on the spin on oil filter. The other plate side has a smaller 1 3/4 in. round raised circle which appears to fit inside the rubber ring on the oil filter. Which side of the plate goes against the engine block or spin on oil filter? Also the kit also has 2 different size ringed rubber gaskets. How do these gasket fit into the kit? Thanks Bill
