Kevin, good "point". The distributor cap and rotor look very new to the eye, but they're probably 20-30 years old, just seldom used. The rotor was definitely on the shaft. I'll check the contacts on the rotor and distributor cap again tomorrow. Even the dump-truck guys said "this thing (distributor cap) is brand new" (from appearance), but I haven't replaced it or the rotor since I've possessed this truck, and that's been 20-ish years.
