I just looked up the application online at Napa. Tell them to look it up as a Chevy with a 235. Any year from 54 to 62 should get there. Only thing is they didn't show any AC Delco plugs, just Champion and Autolite. They should also be able to use the number off one of your plugs and cross-reference. Cross ref for the R45 also shows a Bosch and NGK.
Napa counter help outdone by a 53 year old man with a bad heart that doesn't get enough blood to his brain.
Sad, isn't it.
