Ok I have a bare XS gear housing that I wanted to put my good 1.78 or 2.0 gears from my std 1500 into. I am finding out that I may have a 850xs gear case instead of a 1500xs gear case.

None of my driveshaft/lower water pump bases work in this case. The 850's were set up with helical gears and are slightly different parts in there.

Has anyone tried to change the 850xs gear ratio from 2.3 to 2.0? or even 1.78?

I never thought that there would be such a difference but there seems to be.

I have 2.0 and 1.78 gears to use and two different types of 15 inch drive shafts. (roller and taper).

Any ideas ?

Thanks
