Thanks Ellington -
Today I spray the cap, wires, and coil as suggested. Car ran fine with no change in its' smooth idle. I took the cap off to inspect. There appeared a fair amount of "carbon" soiling the copper. I gently sanded the area. The rotor also exhibited some deterioration. I cleaned it also. Put back together. Runs great (the same). I would gues these components to be original. Anyway of telling? Would it be prudent to replace after 102K. If this cap and rotor was from my 72 Chevelle ($40.00), i wouldn't even think twice. Again do not know yet as to whether I've done anything to "fix". I'll continue to drive and see. BTW, car has new plugs.
