Hi SuziQ
The expensive one doesn’t look correct to me
But it might be stock photo and not actual product
The bottom should rise in the center to clear the manual starting crank option, however if you never intend to crank start it no big deal
Other option is an original radiator from a wrecking yard for $100?
Last one I bought that was the going rate in 2021
Nothing beats original parts for me.
Also for $600 your original radiator if you have it could be made to look new at a good radiator repair and rebuilding shop. Then you’d not only have a good original USA made one but you’d support a local business too!
There is also the mix option, get a quote from a rad shop on fixing up an original wrecking yard rad, they might even be able to source it for you too.
