i checked the VIN plate on my 82 and it says i have a 3.73 rear end but i wanna be sure it hasn't been replaced. so how can i go about checking if its a 3.73 or not? how many teath are on the gear?
Pull the cover,count the teeth on the big gear.Then count the teeth on the little gear,Divide small number into big number.Then you tell us what gear ratio you have :wink:
