Sure if you have a paint code
I know NAPA can mix it, they did the color on my mustang and you cant tell where I sprayed it
NAPA's crossfire is actually pretty good paint too. I used it on my 62 beetle and it was grear.
It may very well be base/clear, the early 80's was a transition time from acrylic enamel to base clear so not every color was yet available in base/clear. Take some 2000 grit and wet sand a small area and see if color comes offwould this have been base, clear in 82 ? or was it one stage ? would the paint from napa be the same ?
