I am getting ready to get my '72 Comet GT moving under it's own power for the first time in many years. I have a D7 3 speed overdrive to install behind a stock 302 out of another '72 Comet GT I owned. I have 3 shifter handles that will work on the transmission and each one has a different size thread for the shifter ball. Before I buy a shifter ball for one of them, does anyone know the shift pattern. I would also like if they were satisfied with the transmission. Since I have the parts already, this is the most cost efficient way to get it finally moving down the road. Anybody? Jim
