My '75 is Mayan Green and I just spent the last few months seaching for factory paint too. The basic answer is don't waste your time looking. You will have to have it custom mixed.

Since you recently had it restored, contact the shop that did the painting. Even if they didn't keep any of the paint afterwards, they should be able to contact the shop that mixed the paint and get more that will be an exact match. Most paint shops record the "recipe" when they mix up a custom color. Having the same shop do it will not only guarantee a good match, but will save you the cost of having the paint reformulated (the work of doing the match is an additional charge over and above the paint).

You can have the paint put in touch up pens or spray cans as well as in a can.
