This is a rear end from an early 80s Chevy 1-ton.  I believe the gear ratio to be 4.10.  Bearings and brakes didn't have all that much wear.  The truck had blown its engine in early life, so the rear end wasn't exposed to all that long of life.  This would make an easy replacement for a wore out 1-ton.  The dually wheels are not bent, meaning no structural damage exposure.  A great unit for the price, plus, it's already been removed.  With good rubber, these rigs will carry one heck of a lot of weight.  You can text or call me at 785 657-zero zero zero seven.  I am usually in a building at a job during the mornings, so make the call after chow time; anytime.  Thanks for looking.
