Thanks for the report, David

Who was the vendor and what were the part numbers?

Do you know what, if any, original differences there might have been on those parts: 47-51 vs 52-53 (no stainless steel in 52-53, maybe)?

Also, for someone reading this who might know know: the 1954 dashboard parts are completely different in shape/finish from earlier Advance-Design (and GMC New Design) years.
