Well my rearend went out today so it wont spin the driveshaft at all.
its a 3.42 gear if its stock.
Ok thank you Kelly
Your rpo codes in the glove box has your gear ratio code. 3.42 is the common one but not the only one. The gear ratio codes start with a G and 2 other digits like "gt4". You can Google them to get the ratio
