I am about to aquire an R150f to swap out my A/T. I have a W56 with the attached RF1A t-case, the W56 needs a rebuild, and won't mate to the 3VZe anyhow.
I would like to get the gear driven RF1A transfer case mated to the R150 using an adapter, that part is easy.
HOWEVER, i understand that the W series output shafts are 21 spline and the R series are 23 spline. so to make this work i would need an additional $140 output shaft from a vender.
Is it possible to take the output shaft from the W56, and install it in the R150 to save a few bucks?

Any one try this?

Thanks

 

no that is not possible however if you want you can cut the different couplers and weld them together not suggested though.

 

inchworm has a 23 to 21 coupler .. if im understanding you correctly.
