I need a source for Oshkosh parts. I am a highway superintendent for a small town and we have 3 oshkosh snowplow truck. Our trucks are a '61, a '76 and a '97. There are all slowly breaking down and parts are hard to come by. New Oshkosh parts are three times as much in price than other truck part. Do you guys know of a oshkosh graveyard or used parts place? Thanks.
