When Shelby transitioned from the steel framed hoods to the
all-fiberglass hoods, a new problem was introduced...
Electro-magnetic interference (EMI) caused by the running engine
that interfered with the radio reception. One method of
remediation was to adhere a metal foil or copper screen mesh to
the underside of the hood.

The other approach to solving the problem was to install (or
relocate) the radio antenna to the rear of the car. Some might
agree that a rear antenna offered better aesthetics too.
The overwhelming majority of these records were contributed by
car owners without providing photographs.
Reviewing The Data
We see an identifiable trend beginning around the middle of
March 1967. This is additional evidence that helps us timeline
when the all-fiberglass hoods were phased in.
