1975 GMC Trucks Vandura MagnaVan Astre Panel Value Van Sales Brochure. Vandura-MagnaVan 1500, 2500, 3500. Vandura gives you two good ways to put nearly everything behind you. When you open the rear doors, you have a 54-inch wide access to up to 296 cubic feet of load space. On the side is a sliding door. It's great for loading in tight quarters because it takes up only 4 1/2 inches of space when it's open. This year, Vanduras feature new optional design high-back bucket seats and a refined six-cylinder engine. Magnavan can have rear-hinged double doors or overhead doors. Next up is the small, nimble, and economical Astre Panel Van which can hold a payload up to 68.7 cubic feet to be pulled by its 2300 cc overhead cam engine. Last but not least in the lineup is the Value Van in Union City Steel Body or Olson Aluminum Body. Very good condition. Note: Canadian. GM 4569 9/74 Canada
