There were 20 white GT 350's that had a scoop light. One of those was a hub cap equipped car. So, we're down to 19. Likley the "press car". Don't recall the number of that one.
It appears there were slightly less than 20 white painted GT350s built with the upper scoop lights.
Cars such as VIN #0025 were not completed until June 1967 (according to SAI documents). The #0025 owner has confirmed it didn’t have the scoop lights.
Another white car was also reported (2011 registry) without the scoop lights. It too was confirmed the previous owner not to have them.
The first white car completed, a GT350, was #0018.
It was equipped with the MagStar wheels (per the SAI PO) as were all of the first ~400 Shelby GT’s built and shipped out of Ford’s San Jose factory.
#0018 was noted to be displayed at the 1966 LA auto show (Oct 27-Nov 6, 1966) according to Chris Brown and the 2017 Mecum Kissimmee auction listing.
The white car with ‘hubcaps’ (wheel covers) is only known because of the photo in the Canadian ‘Track and Traffic’ January 1967 magazine.
It is believed to be #0018. #0018 was sent to Michigan as Ray Geddes company car.
While in Michigan it likely became the test bed for the 15” steel rims fitted with the Thunderbird wheel covers (Shelby center caps inserts).
Geddes (or Shelby) was looking for ways to reduce unit costs with a standard base wheel.
Once approved, production cars were shipped with steel rims as an alternative to the upgraded customer (Shelby American) supplied wheels.
#0050, another white GT350, was also used for PR purposes and first appeared in the ‘Popular Hot Rodding’ February 1967 magazine.
It was not completed by SAI until ~3 weeks after #0018.
