I didn't realize you had straight plugs. That is the difference. Mine plugs are angled kind of down and in.

My current plugs have threads 3/8" (0.375") long. I believe that there is a 3/8" taper seat plug available.
If you by any chance have a photo of the spark plug hole in your head I'd love to see it. Thanks!! |
