Does anyone know if the Saginaw and Muncie speedo cable gear is the same. I put a muncie in my Malibu and it came with the 4 speed saginaw. I need to know if I can just go buy a saginaw speedo gear. The original speedo cable doesn't thread on to the muncie one. So I assume I can just switch the speedo gears? Anyone else have this issue? I have the original guages in the car also. The only difference I assume is that the saginaw one is metric and the muncie is not! Thanks!!!
