A friend of mine has four YZ coded steel wheels that were on his 1963 Corvette. Anyone know the original application?

I think those were for various 1969 Impala-Belair-Biscayne-Caprice models with front disc brakes only.

I believe the date code is K-18-4 on all of them. Would these be 1974 versions?

That would make sense if it's actually a XZ.
or maybe be a later issued service replacement YZ..

What would it be if they are XZ?

XZ is a 14X7 Rally wheel used on 1973 Chevelle-Nova-Camaro & 1974 Nova-Camaro.
YZ is a 15X6 Rally.
Both were manufactured by Kelsey Hayes.

Thanks for the help. Did you mean to say Rally for both codes? These are definitely NOT Rally wheels.

I grabbed one of them today. Here is the stamping.
