Rim/Center Cap Question

[91ChevyK1500]

I have a question on the rims i bought off a friend for 50 bucks. it came with no center caps and I am not sure of the brand of rim, the picture are the rims on my 91 K1500 sport. They are machined aluminum i suppose because I can take mag and aluminum cleaner to them and they clean right up. My question is does anyone know where i can get affordable center caps for these rims? im not picky on the caps, just want the wheels and tires to look complete and not halfed. I am not sure of the measurement of the rims. i have found some caps but the closest numbers that look like they might fit are 3.30" or 3.22". Which is the correct measurement or is there another number? Thank you all for the help! Hope Christmas was good to you all!

They look like first gen S-10 4x4 rims. I think I have a cap for one of those and will look in my shop and measure it.

They are American Racing rims. Not sure of part number for center caps but that style is usually called an "outlaw 2". Hope that helps a little bit.

Get a close-up of the center of those wheels. On many wheels you can run the GM centers held on by duplex lugs. Much better look than the pop-in centers provided by wheel companies,IMO. Those centers can be loose and rattle,too. I agree they appear to be American Racing Outlaw IIs
