Hey guys just an update:
Don has reproduced the FULL SET of RPO ZL2 cowl induction Air Cleaner "Keep Your GM Car all GM" decals.
These are the correct reproductions with correct colors, fonts, codes and part numbers.
GM Original survivor:
Dons version
The decal being sold by others is totally wrong and they don't care:
He has also reproduced the "Late white" version of the CO decal for SS350 L48 without cowl induction ZL2 option.
He is working on the early black and gold version.
