Heater Control Assembly for 1968 Camaro No A/C

[Tommy68]

Hi folks -

I have a 1968 base model Camaro with no a/c and had it judged recently at the Concourse level. I got dinged for having a heater control assembly lens that was a reproduction and that the font was too big. Does anyone know where I can purchase an original heater control assembly lens that would meet the judges' requirements? Also, I believe the GM part number is 3925775 for both 67 and 68 assemblies. Finally, I also understand that the correct 68 lens has a greenish color vice a whiteish one. Many thanks for the help. Tommy68
