is there anything in the vin that would tell me weather its an IROC or just a regular Z28? the exterior badges say Z28 but the interior dash panel says IROC on it. now im not sure if someone just stuck it there or what. so is there any way to tell what im dealing with here?
thanks guys!

 

Check your service label.

 

sorry if ths is a dumb question....but what is this and where is it located?

 

depending on year it could be in the rear storage compartment, or in the center consel under the lid.

 

great, thanks alot!

 

The RPO is B4Z for a IROZ equipment package.

 

or just z28 for years 88-90.

85-86 came with z28 exterior decals and iroc z28 interior decals. i think 87 might be the same
