I am changing the transmission out on my 1984 W350 with 360 motor. I am going to a NV4500 5 speed and will utilize the 205 transfer case. This calls for a different bell housing and possibly drive shaft work also. I need to convert the mechanical clutch linkage to hydraulic. Has anyone done this before and will the hydraulic unit from a 1985 (or later) work? Any advice will be appreciated. Thanks.
