USA Standard Master install kit for a '08-'10 Ford/Sterling 10.5 using aftermarket gears. Part #ZK-F10.5-B. The shrink wrap packaging has been opened, but everything is there and unused. Bought this but ended up with an axle from an '06 truck so needed a different kit. Cheapest price I can find online currently is $350 on Amazon. $275 shipped OBO.
