Are all stick f bodies 3.42 ratios? I bought a oe 10 bolt differential a copule of weeks ago from a stick car that was being parted. I asked the (knoledgeable) guy how does he know it is a 3.42 as advertized? He said (all of the stick cars are 3.42s) is this true? I should have looked at the tag. I think the seller is honnest but I don't want to have it installed and it is not a 3.42. Thanks people.

Just to be clear, I am assuming this rear came from a 4th gen car right? You can verify the ratio two ways. Easy close guess is turn the axles exactly one full rotation and count the yoke rotations. It should turn 3.42 times. Just a hair under 3.5 turns obviously. The second and most accurate is to pull the cover and count the pinion and ring gear teeth and divide them by each other.

this....i used the same method when i was searching for a used rear for my 98 SS w/6spd.......seller explained that what he had was a 2.73 from an automatic f-body.....the yoke turned just under 3.5 times to each turn of the axle hub, making it a 3.42.....i showed him that he didn't know what he had, and he immediately knocked off 150 bucks!!!
