My 1988 calls for an AC Delco CR43TS with a 0.35 gap or an AC Delco professional 1 rapid-fire with a 0.45 gap? Side by side they look identical other than the porcelain portion it smooth? The engine runs better and considering that 29 Years ago the AC Delco Professional-1 rapid-fire were;t available back then. Thoughts?
