Four-Speed Pedal question

In addition to the pedal stuff;
The items of change are the Z-bar, and the throw-out forks.
There are at least 2 different ratio Z-bars, that I have encountered,and several different forks; some ball-stud and some pivot bracket, some long and some short. I dont recall which belongs with what, except that the bellhouse and fork type have to be matched.
There are also several different anchor brackets for the zbars to the Bhouse, and again they are Bhouse specific.
I think the TO forks were clutch specific; one for the 9 incher and another for everything else.
I bet Brewers has all the info you might need.
