Theres a whole range of radiators out there now, from aluminum to brass. It all comes down to how much you want to spend and how much fabrication work you to do to make them fit. Mine was made for a '37 truck but needed side mounts and the lower hose rerouted. It was middle of the road priced so a little extra work didn't bother me. The higher priced units should just drop right in.

Shop around once you find the brand you want. I found mine was cheapest from some machine shop out east. I just Googled the part number then hunted for the cheapest dealer. So many shops sell stuff now, its pretty easy to find a deal if you look hard enough.
