They have no speedo gear....it is magnetic pulse driven. You will need to get
a SLP speedo calibrator box from SLP. Splice it into the output pulse wire of the speed sensor. You then can adjust the signal to the speedometer to compensate for the gear change.

you can get the drive and driven gears from gm parts direct and here is the part numbers:
GM p/n 25513052 (44 tooth driven gear) $12.78
GM p/n 8642620 (15 tooth drive gear) $7.56
the install wasnt too bad,, first pull the torque arm off, followed by the driveshaft, unplug the speedo sensor and remove the tailshaft of the tranny,, inside the tailshaft you will see where the drive and driven gears are,, just replace them and be carefull when you beat the new drive gear on the shaft,, all together it took me about 2hrs to do

Actually you can just change the drive and driven gears in the tailshaft of the transmission. Unfortunately I can't find the GM part numbers for those right now. You can use this website to calculate the ones you need though.
either of you 93 guys over on the speed density board by chance?
*edit* mickeyiz28 got em!!
