Tiger authentication

["Bob, Jerry (LBOB)" <LBOB@chevron.com>]

Who does one contact to get a Tiger authenticated in the San Francisco bay
area, and what is unique about the rivets that they would be distinguishable
from a garden variety rivet?  At least I can do a visual check of my car for
some added piece of mind.  I have the original paperwork for my Tiger when
it was delivered to the original owner, but when I sell it some day it may
be worth having the car authenticated.
