It seems my original inquiry has evolved into a Concours Guide correction.
Glad to be of service to the Healey community. More than likely the hanger
and clamp I ordered from Moss will be UNF threads. While I respect a
restoration where every fastener is correct to date of assembly on the
line, I am not trying to recreate my car to that standard. I appreciate
all the photos of the parts involved even though some have said it is not
on their car and is not exactly necessary. I'm just trying to make it
"look" right in the beginning. If it rusts off after a number of years that
will just like they did originally. That aside, I still have not seen a
photo of the assembly in place on the car. Anyone?
