ok, I'll help you out. The cable b16a's are 89-91 trannys. Therefore the clutch will fit on any 89-91 LS or b16a trannys tranny(A1, Y1, J1, etc.) It WILL NOT fit on any YS1 trannys since they are from 92-93. The YS1 trannys have the same insides as the 94-01 Hydro trannys(s4c, y21, etc.) That is why you can put a hydro ITR gearset inside a cable YS1 case. The clutch splines are the same from '89-'91. Then from '92-'01 the clutch splines are the same. Gimmie some rep since i really need some more.
