Per this chart it looks like Code 60 = WA5236
The original paint was High Solid enamel but they can mix up the same color in any chemistry you want.
When I redid my '87 (Code 72 Apple Red) I asked the shop to mix up WA7475 in base coat/clear coat, hoping for a little more depth and better durability.
It turned out perfect.
