I don’t know the exact mileage on the diff, but it is certainly less than 1000, but probably around 100-200. It is in perfect condition, and as the mileage would indicate it isn’t even broken in completely. This would bolt right in to a ~98+ 1500 Chevy. $250 + Shipping

I have 19 feet of 3x0.120” 4130 DOM tubing that I used for axle tubing. By the foot this is well over $30. My price $20/foot +shipping.
