Joe, I run the 3076 Autolite on my '29 coupe with no problems.
I've had them for about a year and you can't beat the price.
Some "Barner purists" will tell you that they don't look good
because of their small size, but if your car is a driver they are
just fine. If you want something a little bigger that some of
the community would find more acceptable, you could step up
to the Champion W16Y. Either one is fine. Napa sells both of
these plugs.
