Just to clarify, he's talking about an Avanti here; having an
all-fiberglass body, suppressing ANY source of noise is of utmost
importance.

I did not realize it was an Avanti. In that case, I think I would be
worried less about noise issues than making sure the radio antenna had
a proper centerpoise, because it can't use the metal body. The more
_signal_ you get, the more noise you can live with.

My query in a different area. In the sixties, I was always changing
ignition cables attempting to minimize "ignition buzz" on my radio.
(not really a problem since the mid-70s). Back then, I found one type
that worked ok, but I cannot find it any more. (Most of this help in
the 60's came from that Hams, thus I am including them in this
question)

Now for the "new" question.
What "TYPE" of ignition wiring for maximum should I get for my Avanti
(with modern electronic distributor) R2?

Generally, to cut down the static noise (RFI) on older cars, you would
find condensers on the alternator, distributor, wiper motor, and on
the radio itself. There was also ignition shielding and resistor wires
and plugs. The values on the condensers are all different, so swapping
them may cause problems rather than being a remedy. I've never seen any
on a heater or A/C fan motor, but it's also a source of RFI. Even
sliding your butt on the seat covers will create a charge. You remember
those little flexible tails that used to be attached to the chassis and
drag on the ground?.

now this is interesting,
I remember fabricating for my neighbor's '62 Ford a metal can with
braided shielded wires to cover his distributor and cables out to the
plugs. I no longer knew when he drove out of his driveway by watching
the patterns on my TV (UHF).

Now for the question.
Any one know if these boots, if self-fabricated, are essentially a
CYLINDER, grounded by contact with the engine block?

cars, or they can be made with metal tubing slipped snugly over the
metal bases of the plugs.

On piston-engined aircraft the plugs, wires, and magneto
distributor caps are all metal and are grounded. The shielded cable is
grounded at the mag end and the plug end. There's no ignition noise
from such a setup.

Yes. I made some from conduit that extended about 2" above the plugs.
I found it didn't mater whether or not the tops were covered with
metal, but I applied a bead of silicone RTV to prevent the sharp edges
from cutting through the wire insulation. I slit the bottom of each
tube lengthwise to make it easier to press it easier to press around
the hex part of the plug.

Check www.magnecor.com for EMI-reducing spark plug wires.

That's the same outfit that told me they could supply 7mm wires but only if
I wasn't putting the stainless shielding back in place.
