I am wanting to build a 69 Camaro z28 do you guys know where I should start searching to find one in pretty rough condition?

Check your local barns - there seems to be a lot of barn finds the past few months. Look here in the classified section. I believe there are some Z-28 projects. Buy the wheels and deals etc...

You can check craiglist.com but if you want a real Z it wont be cheap in any condition. Even if its not really worth that much it seems that anyone with a first gen thinks its worth its weight in gold.
