    I was wondering if you knew or saw how they mated the 203 to the Allison. Not that I'm going to be able to afford to do it, but curiosity has me wondering how they did it. I know the other thread got a little weird, so I figured I would ask here (or did I miss it somewhere else)?

    TIA.

    Last I heard the plan was to use a GM 203 with the round pattern drilled in it with a 32 spline output shaft in the allison. We sent a 32 spl. 203 input gear for that purpose anyway. It would be similar to adapting to a 4L80.
