I can have the copper radiator out of my 95 F53 in a couple of hours. I've made a living out of my tool boxes all my life and can run with most any wrench swinger. So 8 hours, including evacuating and recharging the air conditioner is over paying.
I guess most people think, if a radiator has composite end tanks, it's an aluminum radiator. Not the case with the older 460 equipped F53s. Go scratch the metal part of your radiator, it's copper.
Also, your OEM radiator has 20 fins per inch and most replacement F53 radiators have 15 fins per inch. That's a 25 percent loss of surface area to transfer heat. Had one, it didn't cool properly. Good luck.
