Stick with the 65 cable shifted transmission. The input shaft isn't a big deal as Cope (who uses PTC converters) can, and has, made 19 spline converters. The rear pump is a cool feature as it allows you to push start the car similar in fashion to push starting a manual transmission. You may have to buy a few gaskets that are not included with the standard kits but they are available. Red clutches w/ Kolene steels is what I use for the street. TransGo2 shift kit is worth it and fairly easy to install.
