When first reading the post I was actually kind of wondering if his car came from Calif until I remembered the first 47 I had in the early 80s was a 2106 Custom and not a Super. I did that very thing in reverse because the 4 planetary setup on that car had one pinion seized and something else wrong.

I was younger then and didn't know any better and when a friend said he had an OD I could have I proceeded to swap parts rather than the entire unit because it looked harder to swap the entire unit. The gift OD was a 3 pinion setup and IIRC it did take one or two pieces more than just the pinion and cage assy.

As I recall, it wasn't a big job as I didn't have a lot of tools or work space then. Didn't change cases or anything like that but maybe there is a case difference and pieces from the larger unit into a smaller can't be done without the case change. I remember the friend was a little annoyed when I gave him back my old pieces and a torn apart OD assy but I was in a condo and had no space for junk parts. It was either that or throw the stuff away.
