Picked these up at a yard sale today, the guy only had two he let go for really cheap, so now I need two more. I believe these are off an '03-'05 Cav or a later cobalt but Im not sure. These are getting painted, so I dont care if they are scratched and worn, just have to be straight enough to balance without too many sticky weights. I found them new on ebay for $90 a piece, and none of the other scrap yards around here have them right now. Any help?

The pic uploader wasn't working for whatever reason...
