Here is a cheep one on ebay http://cgi.ebay.com/ebaymotors/1969-Camaro-Radiator_W0QQitemZ280229599131QQcmdZViewItem?hash=item280229599131&
Even has provisions for auto trans cooler for you non - stick guys.
With mild modification and some new hoses this could be a good replacement for our radiators for those who wish to keep their tgp's in stock appearance. :)
