Dont know how to send pictures in the dm so these are the glovebox codes for a bolt/screw on fender flare kit.​​​​​​​

 

It would be the ZR2 code on that RPO list.

 

I got excited for a minute....

 

I asked him to send me this information. I was trying to see if he had the type of flares I have that were removed from a 97 Blazer 2 door I had. When I removed them they didn't use the big metal tabs like in the rear of a normal Blazer, nor did they use the reinforcement in the front fenders. These are almost identical to ZR2 flares but the only attachment point is along the fender lip. I've been scratching my head ever since trying to figure out what brand or option they are. Another unsolved mystery.

 

Sounds like bushwacker flares, or jungle flares, or something along those... I've noticed that the stock from GMC came with the reinforcement, but others dont...
