90 integ w/b16.. need help for tranny

k i got a 90 teg and i bought the car with a b16 obd-0. tranny started messing up and i got is supposevly rebuild. 6months later my 5th went out. anyways i just purchased a ys1 tranny but had difficult trying to but it on. my question is a had a s1 on it and had bought a clucth. now will this ys1 tranny fit good or what must i do to get it to fit and will it go in perfect? :worry:

you need a new clutch…the splines on the 90-91 are different from the 92-93. a ys1 tranny is from a 92-93 so all u need is a new clutch and u are set.

clutch disk only needs to be changed

thanks guys. ill go get a new clutch disc then
