I stopped at NAPA and picked up spark plugs, they pulled up Autolite AP65 plugs. When I got home, I see the old ones are A64's. The reach looks the same, and the car seems to run fine with 65's.

What do you use?
 
I run those in my TR6. I can tell you this; I don't think they'll foul out.
Ol' Basil has 98k and is bound to have oil blow-by and to some extemt, worn valve guides, yet when I check the plugs for color, they are picture perfect. If RN12yc is useable in a Spit, I wouldn't hesitate to use them.
