It goes on 5 studs/cast nubs that are set into the tranny already, i think it goes on the "middle" piece but i dont remember for sure. It is somewhere in the larger part of the case tho more near the bell housing end.

if you look at the picture next to where it says team rip engineering on the right, its the bottom right part in the picture. It comes on 96 and newer transmissions but will go stright into all other transmissions the mounting studs are already there
