I asked a question about this a while ago, and Chick came through with NCRS guidelines on Delco cap 'R' usage for pre-'70 MY at least. That thread is http://www.camaros.org/forum/index.php?topic=15310
However I didn't learn when the caps changed over from 'Patent Pending R' to having the patent number, so would be great to know that if anyone can clarify!
