I have a 92 Camaro RS with a 700R4 and 26" tires. The factory 10 bolt has 2.73 gears and an open carrier. I bought 3.23 gears and SLP's take off posi. I came up with the following speedo gears to adjust the speedometer: 17T drive (red) and 43 (purple)Driven. I believe that from the factory it came with a 17T drive (red) and a 37T driven(red) for my setup. Could someone please confirm this? I would like to just buy and replace the driven gear. But, these parts need to be ordered and I need to know what I origionally had before I take it apart. Thanks

 

I'm going to go out on a limb here, never having changed speedo gears, but I'd assume you have to change both.

Least it'll give ya a bump to the top.
