    Anyone ever mate a late 465 to a 32spline 203? Just wondering if it could be done if I re-drill the face on the 203? I've got a couple late 465's I can't seem to move and a 32spline 203. Make a strong setup for a doubler :D IMO.

    2: Use a SM465 that was originally mated to an NP208 transfer case. This 465 will have a 32 spline output shaft with a 8 3/8" adapter housing. You'll use a NP203 gearbox with a 32 spline input gear and the face of the 203 drilled and tapped with the GM round bolt pattern to match up to the factory 208 adapter housing. This works very well if you have the available length in the vehicle since the parts are commonly available and the 32 spline connection is very strong and durable.

    I have dubbler mounted to my 32sp 465. I bought the dubbler from someone who had it on a th400. I pulled off my 241 bolted it up and it works fine. real slow :p:
