I was at a old car truck salvage yard here in michigan on saturday and located (3)late 60 early 70's 2 wheel drive c 20 pickups all with auto trans. Two were regular c 20's one was a camper special. The vin off one of the regular ones was CE2409139904 wich according to the vin decoder states it is a 1970. Now how can I determine the gear ratio and if it is what I'm looking for to swap into a 49 3/4 ton for some better gearing?
Thanks in advance.
