Rear end size?
Hey guys...how can I tell what size rear end I have? I've got 4.10's in it and if my memory serves me right, there's 12 bolts on the differential cover... Would this be a factory sized rear end? Someone told me the factory for these years can't hold 4.10's. Thanks!
By the way, car is in the shop right now so I cant double check any of this..but I also think my factory axle code was M, for the wimpiest rear..like 2.73 or something...if that makes a difference or not. Probably not...
