My understanding is that in such EPA strongholds as California, it's almost impossible to get an old brass radiator rotted out and repaired. Same reason the days of the chrome plater are pretty much numbered for all but the biggest shops.
I bought a direct replacement aluminum radiator for my AMX while in SS/H off ebay for less than $200. It fills the entire radiator support opening corner to corner, end to end. Cools down a lot faster than the OEM radiator, and is not that much lighter with water. I'm adding a heavy Volvo electric fan and shroud I scored so I'll bet in the end I save no weight at all but I will have a superior cooling system to (hopefully!), go some rounds in the hot days of Arizona.
