I've got one out of an '83. It's been re cored to 3 row. Not sure if it will bolt in. $50. I'm in Fresno.
It'll bolt in just fine, I'm running an oversized 86 radiator in my 80, and had to ding the bottom a little to make it fit so the 83 should fit nicely. If this falls through I have an 86 radiator I'd sell you.
