Here's the deal: I had to take my gauge overlay off today due to the fact that it was bubbling and the tach needle was sticking. I went to put the needles back on the tach and speedo, but I know that they are way off. My question is, at 60MPH what RPM's should I be around? I do have 3.73 gears in the rear end. Any help would be appreciated, and please don't respond if you have 4.10's because that does me absolutely no good!
