Awhile ago I was able to obtain a SM465 version of the NP203 rangebox portion for use in a "Doubler" kit. It is the 10 spline version, and came behind a 1974 SM465. I've been trying to round up as many factory parts as I can, and the only reason I went the 10 spline route (instead of 32) is because I have several 10 spline trannies laying around, I came across this 10 spline version of the NP203 as soon as I started looking, and the price was right (traded parts). I have not seen 32 spline SM465's readily available in my area. Anyway, getting to the point and question, the female input splines on the NP203 are worn pretty bad. Can ORD supply new or remanufactured input shafts, or is there somewhere else they can be found? I don't really want to look for another SM465/NP203 setup because I know they are not common, and any other one I find will probably be just as worn as this one. I'd appreciate a response, or help from anyone, thanks!
