Product came unsealed with a mess of parts banging into each other. I do not know if all the parts are there or if they are still good to use. No gasket was shipped with this "master overhaul kit".

My 1985 Toyota pickups diff took a crap, ring and pinion gears and everything. Bought this with a ring and pinion off of summit racing, and did it all myself, was quite fun, and now it all drives really good and quiet again. Parts worked perfectly, and they come with koyo bearings which is a really good brand 🔥
