This was off of my company car in the early 80's. The car was a 1981 up to 1983, but I don't remember. I was much younger then and thought cars looked better without hub caps, so after a week with them on I pulled them and stored them in my shed.
I just cleaned out the shed and found them after approx. 40 years later. I want to sell them but I want to identify them properly.
They also offered them as an obscure option on the 1977 Monte Carlo as the Deluxe wheel cover (every year 70 through 77 they offered that year's Caprice wheel covers on Monte Carlos), though the Caprice medallion would subbed with a Monte Carlo medallion when present.
I had 2 of those Caprices, the 350 went for 300K... Those were the days.
Pretty nice set of caps.....Couldn't tell you a price, who has a COLLECTOR 80's Caprice?? Try KIJIJI.....But you never know, put a price on them and see what happens.
