Parchment interiors are addressed in some other places, such as on the '1967 Shelby Research group" in the paint and trim post.
https://groups.google.com/forum/#!topic/shelbyresearch/xMh2RMLAXdcThe white interior myth is addressed in the 2011 registry on page 783.
There are no Ford records showing white interior cars. The numerous Marti Reports I have gathered don't account for any white cars in their totals.
Those totals equal the full production run of 3224 cars (the brochure car #0176 was not ordered by Shelby, so it isn't included in that total).
The only trim codes found in Ford records for '67 Shelby's are 6A black 'smooth', 5A black 'comfortweave', and 5U parchment 'comfortweave')
All of the 5U parchment trimmed cars are accounted for in total and broken down further by paint colors.
The earliest car (parchment interior car was built on 12/30/66 on DSO 84-2539. (All previous cars that were built had black interiors in 6A or 5A trim)
The reason I am addressing the later built black 6A trimmed cars is because those cars are not all clearly identified...yet.
Marti Reports will help us to define that trim in the later June July SJ builds. That is why I've asked for help in the other 6A black trim post.
Additional details and theories on the 6A trim can be found at the “1967 Shelby Research Group” in this link:
