The top of the dash, between the pad and windshield, is zero gloss. The front of the dash is a semi gloss, much lower than body paint, same as interior trim. 60% is a reasonable approximation.

I have the paint chips on my site, and the codes. As long as you live somewhere you can still order lacquer, you can have the original paint formula and color mixed. That's what I did, and naturally it's a perfect match for the areas that were not blasted and were sheltered for the last 40 years.
