Well, I think 'crack the cap' is a bit of an exaggeration. The
'chipping' I refer to is very, very minor. Regardless, your point
still stands, as it is clear that the rotor HAS been contacting the
terminals, even if only lightly.

I think that pretty much settles it, then. There has OBVIOUSLY been
contact so how heavy the contact is doesn't make any difference.
There's supposed to be clearance between the tip of the rotor and the
terminals inside the cap and quite obviously, there ain't any.
The rotor seems to fit on the end of the shaft pretty snug, so I've
come to what seems like an inescapable conclusion:
This distributor is SHOT.
I'm a little puzzled though, about how to go about re-bushing it,
because TRF's Blue and Green parts catalogues don't even list
distributor shaft bushings.
I'll visit the NAPA machine shop down the street this morning and see
if they can do this work.
