Indy swap out in Indy or is it the Chicago swap? A990's are always a catch being that they are rare a probably more so than the 64' aluminum fenders. Aluminum can stick around for decades, where as steel, especially thin gauge steel can rust away easily if not stored away properly.
Definitely Indy. March 3,4,5.
