Normally I would expect Paint  9 JJ. "9" is enamel on Oshawa cars, JJ is solid Verde Green. I have seen on some later cars a 3-element ABC paint scheme where it is 2-tone but the wheel colour is also coded. Not sure how they handled it in the Oshawa plant. "P" is Silverglaze.

Here's my Oshawa '67's untouched, messy factory cowl tag.
