Center caps - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What center caps do I have? I just bought them and look to be NOS but not sure.

Just an edjucated guess, I would say those are 1967 - 1968 caps with out the paint. They also look like they might be for a C20, guessing by how deep they look on my computer screen. What is the overall diameter?

**CarlsLQ9SS** · 02-03-2024, 06:00 AM

10 3/4” outside to outside, 10 1/4” inside to inside and 2 5/8” deep

**special-K** · 02-03-2024, 08:45 AM

What you have are hubcaps. Center caps are what are used on styled wheels. Lil hoodlum is correct. These are 67-68 C/10 hubcaps. The hubcaps for 20/30 series look from the from identical to the 10 series, same diameter. But those are different on the back due to having an inner ring used to accept the clips on the wheels for mounting

Those are 1974-1990 Chevy car poverty caps, mostly used on police package Bel Airs, Impalas and Caprices..

**CarlsLQ9SS** · 02-03-2024, 12:15 PM

Thanks everyone for your replies and knowledge. I agree with 1970cstblazer, they are identical to the pictures you posted. I was thinking they was 67-68 hubcaps but my question is will they work on 68 Chevy truck wheel?

**1970cstblazer** · 02-03-2024, 12:41 PM

I don't think those will work. They require the stamped nubs on the wheel to attach.

IF you have the stock nub style wheels, then yes, these will fit

**special-K** · 02-05-2024, 07:40 AM

These will work on 5 and 6 lug truck wheels the same as they work on car 5 on 4 3/4" wheels. The same is true for all Chevy car hubcaps that mount by nubs, which began in the early 50s.

Most passenger car & 1/2 ton truck caps are 10 1/4 ID & fit on both wheel pattern wheels (5x4.75" & 5x5").

Later 3/4 ton trucks utilize the larger 12" ID caps.

Early smaller trucks (chevy Luv) used a 9" cap.

yep, that's the gospel there. The 9" are what you'd find on the 4-luggers like Corvair and Chevy II. On my trailer, which has 5 x 4 1/2" lug pattern, I have Mopar (which used the 9" caps) 15" wheels with LUV hubcaps

Nope.
S10's & Sonoma's had their own specific caps. The ones posted initially were full-size B-body Impala/Caprice caps.

I tried these on a rough old truck wheel. This wheel is a Chevy 5 on 5 and they fit perfect, thanks everyone for the replies.
