Zerex Original. Available at Napa. Get the concentrate and mix with distilled water.
Old school silicated green. No long life. Many long life coolants will attack the solder in your radiator and heater. Causing them to leak.
Conventional green is an option, however if you don't want to change coolant every 2/3 years you could use Zerex G-05 or G-40 , both are Silicate containing OAT coolants that will not cause any problems in older cooling systems.
I've read posts from dozens of people who have used G-05 for a long time in older cooling systems with no issues, i would use it without worrying.
when i say this ill get yelled at. but on my 65 300 L. i used straight 100% anti- freeze. the only trouble i have with that here in Kansas is if it freezes in the winter. but after some research i found it doesnt freeze hard, only slushy. and -36 F is the frezzing point. and i have lived in Kansas for 70 years. i have never seen -36 F what iam looking for is to stop rust. Mopars DO tend to rust
