Three speeds were all column shift from the factory. Both direct and overdrive. Again let me say that I have installed quite a few floor shift conversions with over drive transmissions. Pictured is an OD that came out of my Y-blocks, but the same setup will work on a Chev. The shifter is a Hurst Mystery Shifter. The mounting may or may not be Hurst. Quite a few manufacturers offered them. I'm not quite sure what Squeeze finds so complicated about this. http://picasaweb.google.com/crenwelgeoil/HurstShifter#5507965444718522434
