The MC code is showing in the 1983 edition of the parts catalog as 73 to 75 and 76 exc. h/per 1st design.
The second code, FU, is not listed. Are you sure it is from a Corvette?
All GM Harrison radiators used the tag.

Thanks. The FU looks like it has an "O" stamp in the middle. Is that MC4 worth anything? Doing some clean up in my garage and tossing out some things.

The photos are fuzzy but under the MC, typically is the radiator part number...can you read it. Tags are not judged and most owners wouldn't know where to look if you asked them. Given the year, the tag code reconciles with a buildsheet. What's it worth? A few bucks, perhaps $5.00.
