Rally Trim Ring Question.

[outlawperformance]

Does anybody know what trim ring this is? GM or older aftermarket.
1. There's no identification anywhere on it.
2. It's was on a GM FW rally wheel.
3. It's 15x7 and 2.5
4. If it's GM a part number would help.
5. I need one new or very clean. One tire fell over in garage and landed on a piece of steel and screwed the ring up.
Thanks for any help. I've tried a couple aftermarket rings and they don't fit the GM rims and the quality sucks
