that tranny gasket to raise compression is a joke cause their is no such thing. it will not leak cause all the fliud goes in the gear casing which is a seperate section from the bell housing which hold the clutch. all b series 92 and up uses the same clutch disk. think it may have a exception when comes to the 92-93 usdm gsr but doubt that. 90-91 cable trannies use a small clutch spline opposed to the later years which uses a bigger spline.
