Fake silver bolt lost on front wheel cover

I had my brakes checked out at Midas the other day, and to make a long story short they didnt tighten up the outer bolts that hold the wheel covers onto the car, therefore one of the silver outer bolt covers has fallen off nowhere to be found. Is there any direction that anyone could point me to to buy either one or a set of these outer covers? Thanks.

same thing happened to me, mad me mad...oh well i dont care too much for those wheels anyhow... U could try autozone, im pretty sure ive seen something that looks like those there, or just buy new hubcaps..

You're telling me. What was Oldsmobile thinking with those ugly things. They have little holes in them! The design must have been drunk that day. Oh, the madness!

Yeah i wish my alero had the alloys, those look so much better
