I specialized in this type truck for 30 years. They are called steb vans. The bodies were made by several different co,s. Aluminum bodies are the best. Union City is the most popular body while Grumman is the best. Chevy calls them double-duty. A good source of body parts is Mill Supply. Call 800-888-5072 & ask for there Walk in van parts catalog. Chassis parts are the same as Chevy 1/2 to 1 ton. We used to drive them in many miles for reconditioning. Make shure its in reasonable good condition. The wind is a trip in one of those. Let us know how it comes out.
