Well... someone swaped the spare tire cover so the option ID tag is incorrect and I need the paint code for my car. It's a '98 Cav that is teal green. Anyone have a teal green cav and can give me their paint code please?

Well. without seeing pics of your car to see what the color is, I can only guess. Since the color is not actually teal, it could be either of the following...

Bright Aqua Metallic Clearcoat 43/WA9796
Dahlia Blue Metallic Clearcoat 22/WA337D

I hope that helps you somewhat. Your best bet would be to go to a local body shop and the paint guy could probably tell you for sure.
