Speed Hunters Project Yankee at SEMA-- 1975 Dart Sport!

This car was swapped to a manual transmission...I've often thought about doing that to my own car but backed off over some misplaced sentimentality over keeping it in the factory's intended configuration.

The truth is that my Dart is worth pretty much nothing as a collector's item...nobody other than me would ever take the time to decode the VIN or attempt to restore it to stock. :p

If one were to do the manual transmission swap like the one in the Project Yankee car, which manual transmission would you choose?
