I have seen several old Chevy AD trucks for sale on eBay with VINs similar to this. I suspect it is a state assigned VIN. 53 probably means 1953, but it may indicate the year it was titled, not the model year of the truck. Does your truck have an ID or Information/specification nameplate on the driver's door hinge post? It should have a serial number stamped across the bottom. A 1953 1/2-ton will start H53 followed by other characters. 53 3/4-ton J53. A 1952 will have a 1 or 2 digit number followed by a K then a P for 1/2-ton or an R for 3/4-ton. Is your truck a 1/2 or 3/4-ton, or a bigger truck? Good Luck.
