How many using an A500 overdrive ?

I bought an A500 out of a 94-95 V6 Dakota. At some point I would like to install it into my 1962 Plymouth Fury station wagon (318 poly engine and A727 trans ) . the big issue is that the 62 Plymouth has the pushbutton gear selector system ( which I want to keep) . A&A transmissions has a converson kit from push button to normal linkage..$$$$ but it's $500.00. Not going to happen in the near future..if ever.
