They did make a lot of 68's, but many of the parts used were a one year only deal. There is not a lot of companies willing to tool up to make parts for such a limited market. 80 some thousand GTO's were made, but that's 45 years ago and many are crashed, detroyed, rotted away or holed away in someones barn or garage. I have owned mine for 30 years, trust me when I say they are hard to find parts for. I'm not saying you can't find the parts, it will be a lot of investigative work, swap meets, buying a donor car or spending a crapload of money for a part that is in decent shape. Search the internet of trunk lids and you will have an idea of what I am talking about. I have never dealt with but try Franks Pontiac parts for fenders, I am guessing about a grand each or more.
