Has anyone tried putting a 203/205 or 203/D20 behind an RBV trans? People have shafts resplined all the time and you can drill the 203 for whatever bolt-pattern you want. So I don't see why you can't have a 2wd output shaft resplined to Dodge 23 spline. Haven't measured but I would guess the RBV output is to small to respline to 31 spline. Then just put a Dodge input shaft in a Ford 203 range box, or run a dodge 203 range box.

Center hole is the same for fullsize or RBV, 4.9". The RBV bolt pattern is actually wider than the fullsize. On the fullsize Ford the bolts are about 1" from the edge of the center hole, on the RBV the bolt holes are about 1.5" from the edge of the center hole. There is no room on a Ford 203 to drill and tap for the RBV trans. But from the pics I've found online a Chevy 203 for a TH350 trans or a Dodge 203 may work. I will have to find one that I can see in person to be sure.

And I guess it wouldn't have to be Dodge 23 spline. it could be resplined to Chevy. What do they use 27 spline? IDK.
