What do these 10 3/16 ID hub caps fit?

[jrblanke]

I have gathered the following information for the 15", 16" and 17.5" wheels:

7 9/16 ID fits 15" AND 16" wheels for 1/2 ton with clips.
8 13/16 ID fits 17.5" wheels for 3/4, 1 ton single wheels with clips.


What do the 10 3/16" wheels fit? are they for 19.5 inch wheels? Here are some pictures I saved from a recent ebay auction:










Here are links to a couple of relevant threads including the 64-66 chrome wheel cap thread, and the wheels an tires for a C20 thread.

Nice caps, they are for 15" wheels with knubs. 64-65. They changed the design in 66 and added ridge around the center and perimeter to prevent collapsing during installation. GM part#3839978 C10-P10

Yep, they are for 64-65, 15 inch with nubs, not clips. I want those. Did you buy them? If not, what did they sell for?

Thanks for the information. I am new to these trucks. I feel like this may have been a dumb question.

they sold for 128 + shipping on ebay. Unfortunitly, I got sniped at the end of the auction and did not win them.

Why did they have two different ways to attach the hub caps? nubs vs clips I mean.

Boy, $128 seems cheap. I should of been watchin'.
Good question on the clips/nubs issue. At first, I thought it was an early vs late thing, but my 63 had nubs and I've seen 64's with clips, so...?

Not sure why the nubs and clips but the clips were used on my c20, so maybe it was just a better more secure mount.
