Matching Parts

Tech Note 1: Small vs. Large Bore
The primary difference between a small bore or large bore, right hand drop, 8 bolt input bolt pattern, NP205 Case is the diameter of the hole for the input bearing. Small bore cases have a 80mm (3.1496″) input hole for TK50119 Bearing. Large Bore cases have a 90mm (3.5433″) hole which will accept either TK50106 or TK50468 Bearings.

Tech Note 2: New Process Transfer Cases
Over the years, New Process used several different castings for GM 10 spline, or 27 spline and Dodge 23 spline transfer cases. If you have a GM 10 spline NP205 from behind SM465 4 Speed or GM 27 spline Turbo 350 automatic transmission with a 8 bolt front adapter bolt pattern OR a Dodge 23 spline NP205, this case is the one for you.

Tech Note 3: Right Side Case
The Boss on the right side of the case is drilled and tapped for a torque rod which was used on most GM applications. The holes are blind and do not extend through the case so if you use a torque rod, you must insure the bolts you use are not too long!
