Hemi 4 Speed ID help

You need to see if you can see the oilite bushings inside the main gears. All original hemi gears had bushings inside. It looks like it has a cut down chevy input shaft mod, which was very common as the chevy transmissions could not take the abuse on a drag car. Also the gears have been slick shifted with the dog lugs on the syncros. There were a few hemi ratios, not sure where my info is right now, but you can count teeth and determine ratios.
