Probably need to talk to Scott about that if that's on the MCA certification test. Have many examples of Sept/Oct '64 convertibles without the braces.
Back to the paperwork everybody seems to shun. According to the "1965 Mustang Body Assembly Manual" (AM0006) pg 9 (the 9 is barely visible in my book), Item 19, C5ZB-16D110-1 (1 req'd each side) plus additional items (20 and AB), were added on a "blurry date" referenced in the revision section (lower LH corner). All I can read is *3-**-65.
However, there's a TSB about retrofits (see attached) - which brings up an interesting question.
If a 64 1/2 or early 65 Mustang had the braces innstalled, which were not an assembly line item, but were added per the TSB, how would that "retrofit" be judged? Some classes - yes, some classes - no?
