J20 Rim ID

[Jenga77]

Looking for some help identifying the rims on my truck. The four of them were on it when I bought it, but I'm looking to get a fifth for a spare tire and want it to match if possible. Also they're a perfect fit and I like the look so I'd like to match any new ones up.

I have J20 axles, so they're an 8 on 6.5" pattern with 9/16" studs, the centre hole is the correct size for the axles. They're a 16x7" rim, and solid, not a split rim. I'm not sure the offset / backspacing. They're steel with a chrome trim ring on the outside. Don't look like they ever would have had hubcaps or centre caps.

Anyone have an idea what these are off of so I can get started looking for another one? I have no idea if they're original or off a Chevy or something. I've searched around but can't find an exact match.

there should be some stamping on the rear side of the wheel with some I.D. numbers you can use for help. need to clean off with a wire wheel to find them. they look like later model chevy rims.

Okay, I'll see if I can find anything stamped into them, thanks.
