The input gear is a stock GM 32 spline replacement and bearing for the 205 transfer case. The gear was used in both the TH400 205, figure eight pattern of the 1970s and the 1980 to 1985 circular six pattern. After 1985 GM standardized on a "long" variety of input for the 205. If this gear is to be used in one of our 10 or 27 spline input conversions, the case needs to machined to accept the larger bearing.
