I'm looking for a Triumph Spitfire for a conversion project (Mechanics Illustrated Centurion)..
This requires a 4 spd w/overdrive (one place it mentions a 5 spd w/overdrive).
I don't know much about the OEM drive train in these cars and in the ads, I seldom see a mention of the Overdrive and all seem to be 4 spd.
Was there a 4 spd and 5 spd syncro trannys with OD??
Is the OD intagral to the tranny or is it something that can be added to a standard tranny?? (The Detroit ones I have had were part of tranny output extension.)
Thanks for any information you might have.
Steve
