Used compressed gas cylinder for a 1969-70 Mercury Cougar or Ford Mustang. This would have been include with the ultra rare, collapsible spare tire option. Originally filled with fluorocarbon propellent under pressure. Tire size was displayed on the decal, so these technically you would want the 7.35 x 14 Good Year brand of space saver and dated steel wheel. These will be mostly empty and for display only. OEM cylinders are approximately 2-13/16" thick. Later canisters are about 2-7/8" thick. These cylinders are very close to propane or Map gas cylinders in construction. Paint one red, and slap a cardboard sleeve with a reproduction decal and close the trunk lid. Dust cap may or may not be included, depending upon inventory.
Original Ford number for the Cylinder assembly is 19C543. The decals for 1969-70 cylinders have a part number of C9WA-19F514-A as shown.
