Awesome, appreciate the input. I found another fragment of a thread where @cruiseroutfit said swapping shafts was straightforward, but no detail beyond that. Kurt, care to chime in?I know it can be done, but I don’t know how. I assume it involves swapping internals.
I did a Saginaw conversion on a 55 about 25 years ago using a Scout type box, and my local rebuilder(long gone now) accidentally sold me a reverse rotation box, which I did not discover until EVERYTHING was installed!
I of course raised hell.
Three hours later I had a box that rotated properly.
IIRC, they said they used internals from a Ford truck. I do not know this for a fact. But I have always BELIEVED it to be true.
