Prairie Sailer,
Howdy. I bought a 1951 1/2 T rolling chassis, which is in terrific shape, from a chap that is putting the body on a Blazer chassis or something. It has the original 16 inch wheels all around and what I believe to be a 4 speed (it's a floor shift). I have a Mustang II IFS and Firebird posi that I am going to install on the frame, so the running gear/transmission are yours for taking, if you're interested.
Cheers.
