Does anyone have one of those dummy shafts for rebuilding the NP transfer cases?

I have a spare case coming my way and going to redo it in the house this winter, and was wondering if anyone used one of these dummy shafts and what it measures. If it is simple, I can make one at work. Just need some measurements to start from.

Anyone????

Thanks as always,
Scott
