can anyone help me identify what vehicle this wheel is off of I'm trying to find new center caps

 

Those are the standard 98-2005 Chevrolet Blazer and S10 4x4 rims. You should be able to find the center caps on RockAuto or many other online retailers. I'd suggest checking RockAuto first primarily because they're awesome, have a great selection, and have helpful staff, and also because they're a sponsor of this site.

 

I've looked on rockauto for them but cant seem to find them unless there not called center caps there.

 

I've ordered them from RockAuto before, but it appears that they no longer have that item for the S-series trucks. Amazon does have a number of different options that might work though.
