Just got a new speedometer cable for my 49truck on a 64 4spd 4x4 chassis,and drive line, it didn't have one before and i cant find were to hook it up to, i heard it hooks up to the transmission but i don't see anywhere to hook it up to. There is a spot on the Transfer but the cable doesn't seem to want to go into it? could the old one just be broke off in there or am i looking in the wrong spot?
