Just so all of these questions are all in the same place...

i've got a question. I've got a ys1 case, A1 gears/internals, potentially a b16 LSD, and need a 4.785 FD. From the helms, the A1 and LS YS1 should have the same gear ratios. will the A1 internals swap into a ys1 case? once that's settled, i'd like to use either an ITR LSD + FD (which i know would work just fine), but i'm wondering if the hydro b16 tranny's LSD and Countershaft/Ring gear will work w/ the A1 gears?

thanks.

 

a1= small spline transmission, and tree style shift forks
YS1= big spline transmission, and independent shift forks(cable version of a hydro transmission)
you can't use anything from a a1, inside a ys1 case! just use the ys1 case, hydro gears, and pick your lsd and your final drive! good luck!
