There are three basic "flavors" of the "cone height" for the pressure plate. Stock Ram Air cars used the "high cone", which in turn, used the "short" TO bearing.
Usually, buying a complete clutch "kit" will get the correct TO bearing. The pilot "bushing" is usually a Chevy, so it won't fit. The part number for the correct pilot BEARING (Pontiacs don't use a bushing) is 7109 (Federal Mogul/National).

Jim,,, I don't understand,,, What do you mean "Pontiacs don't use a bushing" ???... do you mean they use a roller bearing??????.... I was told by the place I bought my 4 speed tranny it's best to use a bushing???... This just keeps getting more confusing.... Do you have a suggestion as to where is the best place to buy the "Correct" setup for my car... Thanks
