My 51 Chevy 3100 has a 350 with 350 trans. and I am using the original speedometer. What kind of speedometer cable will work between the old speedometer and the 350 trans or will the old speedo even read correctly with the new trans?? It doesn't have a cable on it now so before I buy the wrong stuff I thought I would ask some experts. I don't now if I would need an original cable or late model or if the cables have stayed the same thru the years. Thanks!! mitchell
