So i've swapped 2001 gsr hydro internals into my ys1 cable trans years ago, and i remember reading about shimming the differential or something, but I remember not knowing how to do it so i skipped that part. Everything ran fine though, but i'm about to pull out my tranny to replace the input shaft bearing aka clutch housing bearing, so i figure i should probably shim it or at least check the clearance. Problem is, i can't find the forum i used as a guide.

Does anyone know how to do this or even have the specs?
