My '73 isn't running happily.

Replaced spark plugs, didn't change things.
Replaced distributor cap, didn't change things.

Went ahead, and took each of the plug wires, plug an external spark plug
into it. 6 of 8 cylinders produce a spark. The 2nd last on both sides do
not, i.e. 5 and 6 if you count from the left top.

Changed distributor caps. Issue remains in 5 (and 6).

Switched cables between 5 and 7, the issue remains in 5.

I am out of ideas, and appreciate feedback from the combined GMCnet
wisdom :-)

Thanks
