Eaton posi for GM 14 bolt 10.5" rear end

Basically new, maybe a few thousand miles on it, worked perfectly, only selling because it's extra after doing some rear end work. Stored in original packaging plastic wrap and box so it's clean and ready to go.

Part number 19689-010

For gear ratios 4.10 and numerically lower. Used in chevy and gmc from 1973-2012
