gear ratios

Just curious, me and a buddy of mine both have 2000 silverados, both 2WD, and we're wondering what gear ratios we have. Anyone know if theres somewhere on the truck with this info (glove box, door, etc.) I really dont wanna get under the truck and count teeth :disappoin Any help would, uhh..help. :)

go to http://www.gm-trucks.com in there will be a spot to get rpo's this will tell you everything that the truck has. in glove bove is the sheet with all the rpos. gho 3.54:1,gt4 373:1,gt5 4.10:1,gu4 3.08:1,gu6 3.42:1,hc4 4.65:1

thanks man, i knew all those letters and numbers in the glove box had to be good for something. looks like i have 3.42's. guess its time to get some 3.73's
