20” x 8” rim 6x120 post spacing (Picayune)

I looking for a decent used car rim for a full size spare tire.
It doesn’t have to be all shiny.
It’s just a spare rim/tire.
I would like a tire and rim already mounted ideally but if it’s just the rim that will work as well.
The rim is a 20x8” GM rim and it’s 6 lugs with the 6-120 bolt spacing.
Just need one for a full size spare.
Please send me a text message only.
I rarely check email or voice messages.
Thanks,
