Measure the length of the pilot shaft of your original transmission. Then Measure the length of the bearing retainer from the transmission mounting surface. Then Measure the thickness of the adapter plate (1/2 inch 6061 alluminum?).

What you are trying to accomplish is to get the new transmission to look like the old one as far as the engine is concerned. Take the thickness of the adapter plate in to account. If the original transmission has a bearing retainer that is 5 inches long, the T-5 should have a bearing retainer that is 5 and 1/2 inches If you are using a 1/2 inch thick adapter plate. (PLEASE NOTE THAT THE DIMENSIONS GIVEN ARE ONLY EXAMPLES AND NOT ACTUAL MEASUREMENTS) Due to the added thickness of the adapter plate, it is unlikely that you will have to extend the splines to get more clutch travel.
