I have a 47 and contrary to what a lot of people say I can say there were actualy 3 47 chevy trucks. The first being the 46 body style. Latter they changed the body to the AD trucks. The last 47 had a change in the parking break though only a few 100 of them even exist. This 3rd 47 had an SM420 of sorts. It's not like the ones of 48 and latter and its not like the crash box. This transmission is impossible to find parts for and from my understanding the trucks with it were a display only truck. Idk if they could even be driven but I have a funny feeling they can't.
