I put a 700r4 automatic in my truck, which was originally a three-on-the-tree, and wanted to keep a factory look, so I got an automatic shifter mechanism from a 53-54 Bel-Aire and converted it to work in my 55 truck.
I even made up a new "lens" with the characters in the right place for the pointer.
It took some doing, but turned out pretty good.
I did a little write-up about it, if you have any interest in doing something along those lines. Could give you some ideas...
