not sure why the different names either... but the paint covers other wheels & trim parts for other cars. pretty sure this gold was used on z28 rims, cutlass 442 rims etc. & is probably the same basic color as the later WS6 snowflakes too. whats in the oer cans is not a direct match to the original GM paint codes anyways, just a very close acceptable color for all but 100 point concours restorations.
