I am restoring a 1974 GMC Jimmy with the SM465 to np203 combo. I have just realized that the 10 spline output (male) of the 465 and the 10 spline input (female) of the 203 are almost destroyed. I can find plenty of 465 mainshafts, but absolutely zero np203 10 spline input shafts! I have read that they are rare, but I’ve got to have one. I found one company that made one at one time, but they are out of stock.

Yes, the various 203 inputs interchange. I also have an ORD short 32 spline sm465 output, great product.
