Another radiator recommendation needed...

I have an original 1967 Pontiac Firebird 400 4BL MT non AC with original engine. The water runs hot (180-220) with 15 minutes of driving, so I’m thinking of replacing the radiator. The fan shroud, fan, spacer, etc. are all original and to specs. I don’t want to run an electric fan, so I’m looking for the best radiator out there that will hopefully bolt up without needing any modifications. Something close to original, but I’m willing to modify if keeps the temperature down. Any suggestions? Thanks!
