Ok, on my 92 rs, it came factory with the 3 piece spoiler. I took a high rise spoiler off of my 92 z28 and got it all bolted on. What is the best way to fill in the extra 2 holes on either rear quarter panel from where my 3 piece spoiler used to be?

 

Weld them is pretty much the only right way

 

Take an old body panel and use pieces from that...
