Quick Time bellhousing

I am in the process of mating my trans and bell housing and notice some items I'm not sure of what or how to use them. For any of you who have used the Quick Time C180L bellhousing for a TKO/T-5 tranny, ,some questions. There are two adapter rings that came with the housing. One looks steel and the other brass. The brass has some slop around the trans boss and the steel one seems tight. I'm assuming I use the steel. Also there came with it three what look like fulcrum plates and two screws to secure to the housing. How do you decide which to use. And what is a good starting point to set the adjustable fork ball pivot initially? Thanks for responses. Nick C
