I have a posi disc to disc rear out of an '88 GTA , with 3.08 gears. Unit was removed from vehicle at 43,025 miles. This unit is priced to sell at $ 175.oo
or best reasonable offer. Unit does not includes calipers due in part to it being sold so cheap. Excellent working order sold as is and all sales are final.
You won't be sorry this unit hauled some AZZ.........



P.S. If you don't know what a diff looks like please don't waste my time wanting to see pictures, if you really need to know what it looks like look under any rear wheel drive car to get an idea.
