'After 126th car the Ace Bishop worm and sector steering box was replaced by a Cam Gears rack and pinion system' [Cobra Register Introduction].
Nick’s maths are beyond reproach: 2125 is the 126th car and 2126 the 127th.
Of more interest is the timing: 2126, the first R&P car, left AC on 31 January 1963 but AC made another 46 Worm & Sector cars in February to July 63. Why did Shelby customers keep buying W&S cars when R&P was on the cards? Two reasons:
First, although the first AC R&P car left Thames Ditton on 31 January for US approval, Shelby and FoMoCo didn’t give the go-ahead until later in February and the next two AC R&P cars (2127 & 2128) only left Thames Ditton on 7th March for air-freight to Los Angeles.
Second, though, and more importantly, Shelby didn’t start marketing R&P cars to the general public until most previous stock had been sold and the demand for R&P race cars and Shelby/FoMoCo demonstrators and PR cars had been met. The first 22 R&P cars (not exhaustively checked) were race cars, demonstrators and PR cars so the lowest-numbered true ‘customer’ R&P car was 2148, ex Thames Ditton on 11th July 63 and sold by Shelby American to Julian Harrison Inc on 12th September 63.
In summary, AC shipped their last W&S cars on the 1st and 2nd July 63 and their first R&P customer street cars on 2nd (2150), 10th (2151, 2 & 3) and 11th July (2148 & 9).
And what of the COX/COB cars, the subject of this string? They didn’t start till October 63 and are all R&P: AC’s W&S production ended three months earlier.
