Is this a 69 Z/28 rim? K10 3 9 YH

It was on my car with a FW code "K16 9 FW" rim (Monte Carlo?)

I don't want the YH and don't need it but I would like to know what it is...

The YH wheel is a 15x7. I have them on my 69z.I am looking for one for the spare and will buy it or trade you for something you may need. You can E-mail me and I'll be glad to call you right back. Thanks, nashcar.
