    My neighbor did the reverse a few years back. He took the automatic 200R4 out of his 87 Monte Carlo and put a Ford 5 speed in. he had to make a few trips to some junk yards and Chevrolet @Carlisle got the pedals and the linkage.

    In your case it would be the reverse, I'd go to a few breaker yards, or hit some of the auction sites and get your automatic pedals and a gear indicator, I'm willing to bet your dash is already has the space for the indicator in it. The rest is just finding a column and a good 700R4 transmission for it.
