Have a some questions concerning the 1965 Cobra 289. Were all of these 1965 289 Cobra Mark IIIs? I have been told starting in January 1965 the 289 Cobra was built on the Mark III platform. Is this correct? If so are there any 1965 289 Cobras produced before January 1965 that were Mark IIs? If so what's the main visual difference between the Mark II and Mark III 289 Cobra's? Is the 289 Mark III as wide as the 427 Mark III?

Thanks for any info you can provide.

Pete...
