i looked in the archives and they basiclly didnt help me except to say its from a bseries and its hydro.
it has the shaft in the dif, so i kno its non lsd. the sticker reads s80 then a no. code. is there neway to find out by no. of bolts on bell housing, casting marks, any thing that points out that its a gsr transmission. it was on a b18b, but the guy that sold it to me said it may be a gsr transmission. i need to know before i buy an lsd for it. i can get pics if it will help
