[60-66]

Heres a real deal NOS 1/2 ton clip GMC Version of that cap Factorystock . Note the red paint , GMC ONLY , Chevy was all white .

Your right, no red paint on Chevy caps, that is rust!

i have a front set of chrome GMC hubcaps , they came on a 1965 GMC 3/4 ton truck, (K1500) that i bought from a fire dept in pennsyvania with only 11,000 miles on it . these were on the front end , 4x4 it says GMC on the hubcap and it looks like they were cut out at one time , either from the factory or the dealer , the truck did have the chrome package , the back side measures 8-3/4" and the front hole measures 3-3/8 thought i would supply this info if it helps

Interesting , most likely added by someone at some point in the trucks life, being that these are 1962 and 1963 only caps. No hubcaps offered 64-66 on GMCs . Would be interested in seeing on the truck without the black rubber .

Is this in any of your data books Jon? I believe they were offered up to '64- '65 model year GMC 4x4's. I agree with no caps on '66 4x4's.

The proof is in the GMC parts books , I do believe it was also mentioned in the Data book also . No hubcaps for K series in 1964-1966 . GMC went to 1963 but Chevrolet 1962 was the last year.

Yeah, data books would be the last word. I might have been suckered by a July '65 Fourwheeler magazine that showed a 4x4 suburban with caps. Any owner could drill out the centers, even a dealer back in '65 to please a finicky customer. Note, optional mirrors are stainless steel Prutsmans, a GMC only option ( another ahead of the competition option from GMC).

Period era photo judging by the car nearby, appears to be a '60 or '61 3/4 ton. I do see a much smaller hub piece that were used to seeing protruding from the center of hubcap. The plot thickens

60-66 with your parts mockup you did do you have a spare full time hub to throw on and try a standard cap vs the one with tiny hole? Looking at the gap you have before cap would be on it doesn't look like there would be enough clearance for the little nub on flange to stick out on standard cap.

The previous red '60-'61 photo, IMO, is what the '62-'63 cap was designed for. Needless to say, more era photos would be nice to solve this mystery.

I don't know , that 61 cap is a short profile cap similar to the 64-66 style . I tried that on my old 65 K20 and no hole was needed . With the 62-63 cap being so tall it clears fine . There again this 4x4 hubcap is in the parts book as a 1962 only part number . I think they figured out they did not need a special hubcap for 63 and stopped making it. Just a thought

This factory photo shines some light on 3/4 ton 4x4 hubs. IMO, a specific wheel size must required a cap with a hole, where as, other wheel sizes did not require a cap with a hole.

If you go back to post 10, it says in the parts book that the cap with the hole is for 17.5 and 19.5 wheels. Great photo FactoryStock !

If you look back at post 27 , notice the 2 inch spacer needed to run lockouts . If you remove that and put on a full time cover , a normal full wheel cover fits right over the top without a hole . Then look at post #8 and you will see a truck without lockouts and a full wheel cover .
