I’m a 67/72 guy and don’t know much about 73-87 stuff, but while sourcing some dog dish hubcaps for my truck I ran across a guy who has literally hundreds of hubcaps for Chevy/gmc trucks from the 60’s to the 80’s. What are the rare/desirable caps from these years? I’ve heard K20-K30 caps are rare and difficult to find, what do they look like and measure? Anyone have any pics so I can know what to look for? Thanks!
