1978 GMC Grumman truck

1978 GMC Grumman service truck. Very spacious cab. One new leaf spring pack and distributor cap. All lights work and transmission shifts fine. Some rust in drivers step and service body. Steering box adjustment needs tightened which I will do. Has not been on road for a couple years but drove 3 miles home just fine. Should be no trouble passing inspection. Very good tires. brakes. exhaust. frame. Wipers not working probable due to a bad switch. Passenger window can be lowered and raised but not by crank.
