Advance Adapters Full Bellhousing Adapter Kit For A GM NP205 (27 Spline Transfer Case) To A GM 4WD NV4500 Replacing A Turbo 350 This package is for a GM 4WD NV4500 to the GM NP205 (1971-79), replacing the TH350 transmission. This application requires the shortening of the New Venture output shaft to 4.498 inches in length. When using this kit, we couple to the 31 spline area which is under the harmonic balancer. In order to cut the shaft, you will need to remove the tailhousing. The NP205 has a 27 spline male shaft. We manufacture a female coupler that engages the 31 spline transmission to the 27 spline transfer case. We have included a new seal for the adapter housing along with a new sealed bearing for the transfer case for extra protection. The transfer case adapter kit uses two castings to couple the NV4500 to the NP205. these castings have been machined to allow for proper transfer case shift rail clearance. A shifter bracket has been provided to mount the stock NP205 shifter handle; however, you may be required to modify the handle to properly fit up into the cab of the truck. The bellhousing in this kit bolts directly to the front of the NV4500. Since this vehicle was originally equipped with an automatic transmission, we've supplied a slave cylinder bracket for your clutch linkage. This bracket is designed to fit 1985-91 GM slave cylinders. A hydraulic clutch system is much easier to install that a mechanical linkage. If you decide to install a mechanical linkage, you can substitute for bracket 715534. The overall assembled length is 26.750 inches. Kit Includes: - 712576 - Bellhousing kit for GM NV4500 (1996 and newer)
