I have been posting on the 1st generation forum about this and gotten some excellent help. I have been told that (by people on here, and my local shop Scheid Diesel) that it would not be a problem to install a getrag from a similiar truck, needing all the clutch cables, etc. My question however is, is it possible to install a newer NV4500 in to my 1991 w250? How much of a problem would it be if its harder than installing a getrag?

I dont really hear anything good about the rag so I want something better.
Any help is greatly appreciated.
