greentahitianlshatch

I have a 91 ef hatch with a 92 ls swap and the tranny went out a few months ago....I am now stuck in another state in college and trying to get her back together....My buddy found me a tranny but he doesnt know what year the swap was he got the tranny from....I know it will bolt up fine but from the info I found searching I believe the clutches are diffent between 90-91 and 92-93. Well I want to order a clutch and I dont know what year to order because I dont know what year the tranny is....I know honda didnt do us a fav in stamping the trannies very way but is there a way to tell the year....I am guessin the only difference is the splines on the input shaft.....any help would be greatly appreiciated..... peice......
