CRAGAR reproduces these today,in both uni-lug & single dedicated bolt patterns,for a very reasonable price.
Of course they're not exactly as tailored 45 years ago,but some don't mind so bare that in mind if deciding to re-plate.
Dave just sold a nice clean vintage set of 4 recently on here for $800.
