I always struggled changing this spark plug, so I drilled the hole in the inner fender apron, and it works like a charm.
The hole's not angled so it must be a straight plug.Straight or angled plug?
Headed primary tube size?

I think it's a neat job. You can easily get a solid grommet to put in the hole.If I did it again I would go 3/4" space instead of 1/2" next to shock brace
Yup. After some primer and touch up around the hole.I think it's a neat job. You can easily get a solid grommet to put in the hole.
