I bought a rear main seal kit in case my leak was related when I pulled my transmission for replacement. Turns out I do not need it. Fits many years and vehicles. Ordered for a 2001 Suburban with a 5.3
I have a Fel-Pro BS40640 kit with seal and cover gasket, as well as a Melling MOGP100 oil galley plug. It is recommended to replace the plastic plug when you have the cover off. Look up part numbers to see if they will work for your engine.
New in box, have not even opened it yet. Both items can be yours for the low price of $40.
