Based on the AIM manual and other sources ground straps are run from the exhaust to the frame. Anyone understand why?

The motor and frame are already ground why the exhaust?

Thanks

All the grounding straps are only for radio reception clarity. The straps are only used on cars equipped with radios, as AM radio is subject to interference from any source of static discharge. They really went out of their way to avoid any possibility of static discharge between any two parts of the car.

Not that it needed confirmation, but having a Radio Delete vehicle, I can attest to the fact that I have NO grounding straps.

Finally, something I don't need to spend more money on.

Eventually cause the sealer paste on the exhaust pipe coupler COULD interrupt the grounding for the back end of the silencer system?

sealer paste? I've never heard of such a thing on an OEM system, just on sloppy work by an aftermarket shop....

I have a 66 that was assembled without a radio but, strangely, it does have two ground straps at the center crossmember exhaust pipe clamps. Always been there.

There's no body ground strap at the left side #1 body mount and there's never been a hole drilled in the frame for one. Surprising because I thought all frames arrived at the plant with that hole already drilled.

Also a pic of the underside of the body that shows no hole for an antenna and no patch to make a fake no radio car.
