what up everybody, im new to this forum stuff but heres what ive got

b16a first gen with y1 tranny, on arrival the trannys differential case was cracked which made it pretty obvious that it was useless so im swapping the originial s1 tranny differential case with the new y1....my problem now is i cant find a single diagram on how to put it back together....is it the same as the s1 and the j1 besides the gear ratios?
id appreciate any help i can get
