I bought it

Do yourself a favor, and get a gasket set for the trans , guarentee it will leak if you don't! There are O rings on the shifter fork arms in the side cover, and, never put rtv on the gasket surface of a transmission, that being said, go to Brewers Performance, or Passon and get the seals, both great to work with. Gaskets, and seals are cheap, the rest of the thing's you need are easy to find at local parts stores, or mail order performance outlets. Just my 2 cents, I learned the hard way, after rebuilding many of these, Good luck!
