Here is a copy of the 1966 Pontiac PPG color chart. It shows Tiger Gold as a "-" (dash) for the data plate paint code. The dash was also used for many other special paint colors. I have seen the "1" on other 1966 data plates, and have heard it was used for Tiger Gold in 1966 along with the dash. So different codes for special paint may have been used by different by Fisher Body Plant locations, not sure. As stated above, the best way is to find hidden location where the original paint still exists and match that if you want to be as original as possible. Jim
