Take old radiator and reuse the old tanks and brackets and have it recored.

You live in Wisconsin, not particularly hot or humid. Buying an aluminum radiator is a band aid to the real issue which will remain unmonitored and unresolved. (Thermo wrong, poor fan spacing, slipping fan, incorrect pully, bad cap, rotted or poor divider plate spacing, wrong depth ion shroud).

Lets look at the principle here.

Now he has a new shiny aluminum radiator which works, but not as well as if he had fixed the problem causing the overheating initially. Could it be "just" the radiator and blocked off/clogged fins? Sure, but unlikely.

You lose 1-5% a year in efficiency from a cooling system from coolant breakdown to degredation of radiator from crap hitting fins, blockage etc. Your nominal running temp should be 200, everyone likes 180 so we will use 180

Brand new radiator, cooling system, radiator, thermo..fresh cooling system.

Over 20 years and say 4 coolant changes only, minimal loss of efficiency is 20% (wear of all hard parts) 180 plus 36 degrees is 216 degrees.

Fix the "problem" and not cover it up with a $500 band aid.
