D19 spark plugs

What is the modern equivalent of the Champion N-8 listed in the parts manual?

NAPA's website lists five different matches for D19 spark plugs, and some of them have different reaches into the cylinder.

**** D-19's used AC Delco 45XL or 45XLS which are 3/4" reach. Figure it from there. R-45XL or R-45XLS will work.
