Ok, I'm a believer, for the 1964 COBRA application. I'm left wondering what other Ford applications this alternator was used on, if any, or was it unique to the Cobra... It is a safe bet to say MOST Ford products didn't even have alternators until 1965.
Lyn Parks original survivor 289, they don't get any more 'real' than this.
Note the unusual exhaust 'headers'.
