Transfer Case
 
Jeep Dana 18/20 transfer cases must have a 6 spline female drive gear. The transfer case bore size must be (4”) large hole. The Dana 18 kit fits large hole transfer cases only. Transfer case shifter linkage will need to be modified in order to fit alongside the large 5 speed transmission case.  Additional information can be obtained in our on-line catalog, Jeep & Scout Vehicle Section: Transfer Case Information, Jeeps 1974-79.

Some transfer cases require the stock linkage to be modified for clearance on the NV4500 case.

Transmission
 
The adapter kit is designed for exclusive use with a GM NV4500 4WD transmission. Several adapter kits require you to shorten the existing transmission main shaft while it is still in the transmission case. This is common when a 4WD GM NV4500 is being used. Each instruction sheet gives the exact cut off location
