Ok guys i have a 82 k10 with 35s on it my rear end just went out and im not sure what size the gears are the guy i bought it from said the guy before him changed the gears out to help with torque. Is there a way for me to take the gears out and tell what they are and what would be a good size gear to put it in for off-road and on road use that wont cost alot and what all would i have to do to put new gears in it.
