Sorry, looks like my ad, can't seem to find the magazine for date, however these wheels came out in late 1963 in the aftermarket for 1/2 and 3/4 tons of all makes, when camper craze began. These rims could have been special ordered from '63-'66, as your K 20 indeed was. They were a standard option beginning in 1967. What is interesting is that the manufactures, either Kelsey Hayes, Goodyear or Firestone, used the factory correct 17.5" centers and just rivited on a generic 16'5" wide base drop center rim. In other words, the part the hubcap goes on is a factory piece and has correct offset. Here is a '60 Chevy with them, but, must have been put on at a later date.
