The original spare wheel used for 1978-82 Corvettes was a 15 X 5 wheel with code "YA". It was GM #472545 and it's GM-discontinued. From what I can tell, this was a Corvette-only piece.

Thanks - any info on the tire size?

Joe-
Thanks for the info. Do you have anything on the spare tire? I need a spare but don't want to buy something that won't fit under the car.

I believe 1980-82 used P195/80D15 as the spare tire.

Is the spare stamped with "YA" or the PN?

Was code "YA" or the part number stamped anywhere on the wheel?

The "YA" code should be stamped somewhere on the wheel, likely near the tire stem. I seriously doubt that the GM part number was stamped anywhere on the wheel. It's not beyond the realm of possibility, but highly unlikely in my opinion. I've never really scrutinized one of these wheels, though.
