Seeking input on radiator replacement for 1977 GMC 3/4 Longbed

I guess a lot of your choice has to do with the climate where you live. In HotZona I have never had more than a few years without copper/brass leaks. I just replaced the aluminum/plastic radiator in my 2002 Cavalier with 146,000 miles on it (the original radiator) and that was because it was clogged up, not leaking. The AC Delco replacement for that radiator was right about $100 delivered from Rock Auto. I think I got about $8 for the aluminum scrap from the original radiator.
