Tbolt,
If you are talking about the red paint on 65-66 Konis, I had a paint company here in Texas
mix the correct color from the bottom bracket on an original front Koni dated 4-65.
If you send me a personal message with your email address I can send the PPG formula.
I have used this on the original Konis on my 65 Shelby and sevaral friends have used the
same on their 65s.
