Just picked up these two from an Oldsmobile guy who got them from a guy who had them in a drag race 69 Camaro back in the day. First one is a B-Body Hemi trans XS29L9B242253 input shaft was starting to be cut down for the Chevy, but looks very clean inside, probably low miles looks like it was not touched inside. Second one was in his car when he raced it, aluminum case and tail shaft that had the B-Body pad ground off and input shaft cut down. Has home made rods and super shifter, I did not open it up to look inside. There are no numbers but casting numbers on the aluminum case or tail shaft. Have no idea what this stuff is worth...

Not sure if these are sold as I made but ive run several hemi 833-s the non mopar guys worked over. Just bought the crank hub insert and made the "Chevy" sized bushing and pressed it is.

You really want to open the AL case unit and see if it might be slick shifted and if so what shape its in and if its a home made unit or bought parts. Who knows might have some liberty gear parts in it.

Also look at the AL case good to see if the shafts that ride in the case are holed out or if someone got smart and bushed them prior to building it.
