After this van was listed I gave the codes from the fuse box area of the cab to a Corvair guy who then supplied me with the following information.
5z60e. "Z60" is the option number for the Deluxe features of the van (internal vinyl panels,etc), nd the "e" indicates that the deluxe features includes the two rear armrests, hich were only part of the package when a third rear seat was ordered from the factory
5532f. "532" is the option number for a two-tone Jade exterior -- yours looks original -- and the "f" is a code that told the paint shop of the assembly line that this vehicle would get two tone paint.
The prefix "5" of both codes specified that this was a forward control Corvair vehicle.
