Use with Engine Mounting Bracket BHS5118, and Anchor 2638 Transmission Mount, 1985-1987 NP208 shifter assembly, and 1985-1987 shift linkage rod. Modifications to the transfer case input shaft is required when the output shaft of the transmission is not splined deep enough to allow the transmission and transfer case to be bolted together. This is common with 545RFE transmissions. The procedure is relatively simple, does not weaken the transfer case input shaft and is outlined in the instruction sheet. This Transmission mounting bracket kit was designed specifically to install the 545RFE transmission and NP241D transfer case with GEN3 Hemi Engine swaps. It is for use in 72-93 W100 and W150 pickup trucks originally equipped with V8 engines, NP435, NP445, or A727 transmissions. Other base vehicle combinations may work but have not been verified at this time. Engine and transmission driveline inclination angles are acceptable for stock ride height and vehicles with up to 3 inches of suspension lift. Driveline and U-Joint operation angles should always be checked and corrected, if necessary, for your particular application. Uses OEM front and rear drive shaft from NP435 4 speed or A727 transmission and NP208D transfer case combination. Uses OEM 85-87 NP208D transfer case shifter and shift linkage rod (shifter mounting bracket supplied with BH5151 kit). *Drive shafts and components from other transmission transfer case combinations may work, but have not been verified.
