I'd say it's $600 of one or $600 of the other....!!!
The originals are alleged to be fantastic radiators.......
I put a new aluminum one in ONLY because my original was long gone and mounts were already modified (not to great standards..), not to mention all the fan stuff was cobbled together too.....so it wasn't like I was "changing" anything from stock.
I would like to see the original style maintained if possible. But that's me.
If they can get you the same style of core, with all the fins etc, that would be great!!!!
Fans could probably use help however. At very least, take originals out, lube the bronze bearings with oil, and seal up any air leaks around the radiator so air doesn't bypass it!
