When getting a new oil pan, don't forget the bolts. We carry this package of 20 brand new zinc plated 5/16" bolts which feature an oversized flange to spread the load out to the oil pan rail and make sure the gasket is held firmly and evenly. The flange is also serrated to ensure the bolts lock in place and won't "back off" due to vibration. These work to attach any oil pan to any engine, and are also compatible with windage trays.
