You are going to have to fabricate some brackets to use that radiator in a hot-air with the stock fan shroud. Or you could use the top plate from an Olds V-8 G-body and use the Ramcharger/Intrepid electric fan or the stock fan set up from an IC car. The aftermarket replacement radiator is available in a plastic/aluminum version that will mount in place of the stock smaller hot air unit if you're not into doing a lot of work. Plenty of options when it comes to the cooling system in our cars.
