Help identifying this 427 Cobra on the Braille Rally...?

[SunDude]

Lew Spencer drove a 427 Cobra street roadster in the California SCCA's Braille Rally in the mid-to-late 1960s. As the event name would suggest, Spencer's navigator Ken M. was blind.

I haven't yet been able to identify the serial number of this particular Cobra, or the month/date the rally took place. The two round taillamps would place it somewhere in the CSX3200-3300 series.

I would appreciate any information that would shed some light on this.

UPDATE: I've found two small articles that confirm the event as the 6th annual Braille Rally in Jun/Jul 1967 (exact date TBC).

One item is from the Jul 1967 issue of the Cobra Crier (Shelby American staff newsletter) and the other is from the Sep 1967 issue of the SCCA's Sports Car magazine. Am still trying to ID the Cobra, one of two entered in the rally.
