Try like $400 plus bucks, Hey trust me if there was that much better cooling out of them I would have bought one, lord knows I buy enough bling for the quads, call around a few radiators you will find some that do Quads Radiators and will be just like new, think about the calcium deposits, gasket material, RTV floating around for the last 20 years, and don't forget to make sure you put your that lower air scoop back on too.
