Probably not exceptionally helpful, but per the 1967 Shelby Research Group files:
B.J. Werner, Inc. (a/k/a/ Werner Ford)
450 River Drive, Garfield, NJ
Phone: 471-1111
Looks like they were in business from 1948 until sometime in the 1970s.
Ford Dealer Code: 15B011
Shelby Automotive District Code: 6B09
Not a franchised Shelby dealer in '67 or '68.
They only sold a single 1967 Shelby G.T. and it was shipped to them on 6/26/1967
