I'm looking at this Z28 on the end of my street that is sitting in this guys yard and its forsale. And the odd thing is the Bagdes don't look like they quite fit right. The RS and Z28 and IROC Z place holders in the gfx are different shapes correct?

 

They should be the same. On a 91-92 you can swap the RS for a Z28 emblems. and I think it is the same for 90 and below.

 

Yep the same, he must be an idiot and stuck them on wrong.

 

I ran the vin number this afternoon, its an RS

 

Unless it is a V6, running the vin # won't tell you whether it is an RS or a Z28. Of course a V6 vin would obviously be an RS.
