So a few things I'm unsure of...
The RF1A case has a bearing on both sides of the gear set, and the output shaft of the 4500 does not require a support so I don't think you will be needing that bearing in the adapter between the two.
However there will need to be a seal between the two boxes.
I'm assuming your plan is to cut that 4500 to land cruiser adapter output shaft down and using it for a spud shaft?
Is that shaft 10 spline?
I'm not sure if the shaft is hardened enough on at the base of the splines, or is it will run concentric enough for a seal, but that's probably where it's got to be.
Something to think about
