Mounting Lokar Shifter to 350 Turbo Question

[buildinga55]

I got my transmission today and the shifter that came with my truck, a big pile of parts, is a Lokar 4 point mount shifter for a 350 turbo. I just sat it on the transmission and all the bolt points line up, but there must be a missing part or something. The front mount of the shifter have indentions on the sides of the transmission case, and the mount is threaded, is there supposed to be some kind of stud or something that fits in the hole on the side of the transmission. My finger is pointing to the hole I am referring to. I just have the shifter laying on the transmission so you can see what I am talking about. Thanks for any help
