transmission side all 90-01 integra are the same and as for drivers side you can use auto or 5speed thay are both the same on 90-93 and 94-01 integra.only the halfshaft is different on 5speed/auto if you useing the halfshaft that is coming with the tranny((it has 1 male side((tranny side))and one female side then you use 94-01 integra..i recomend if the crx is lowered Use the axels with ABS thay are about 1/2"longer and help camber
