speedometer problem
The rearend in my truck is a newer 9'' 28 spline geared to 3.25. I have no idea what was in it before. I need to figure out if i can adjust the speedometer for it or i just have to get a new one.
Correct me if I am wrong members but when you do this can't you just swap out the plastic gear on the end of the speedo cable? Theres a plastic gear on the end that goes into the tranny and you can swap it out for one that has different number of teeth. I got to figure that out also as far as which one to get ,my rear end is different from original.

Speedometer Adjustment
I recently installed a new C6 in my old bug. Speedo is off by 10mph. It really felt like it was off but to be sure I checked by driving by one of those roadside speed reminders. I was at 30mph and the sign said 41. I had a 17 tooth gear in there so I tried a 20 tooth and its off more now. I will try gears with fewer teeth until I get closer. Any one have a 14 or so tooth gear to swap?

William, like I said above there are many charts on line to help you find the right gear. Work smarter not harder! Here are a couple examples:

Oh, and I forgot about the color coding on the gears. I think they're all like that, not sure though.

Here's another. Disregard the fact that it's a Chevelle site:
