Triumph Spitfire - Gearboxes

Are all of the non o/d gearboxes in Spitfires the same?

Are non o'd Spitfire boxes the same as the Dolomite boxes?

Can the Marina or Midget box be used in a Spit (with the Spit bellhousing)?

Daniel:

Here's your answers:

Question 1. No. If we are talking about Spitfire 1500 models, then you can assume that all non-overdrive gearboxes are the same (they will bolt on). Early Spitfires used a different gearbox which may interchange with Triumph Herald models: rule of thumb, if you have a 1300 engine in your Spitfire and you find a 1300 engine in a Herald, then there's a good chance that they will interchange.

Question 2. Not sure. Thought that Dolomites had the 77mm boxes. If so, they don't interchange. You can always experiment. Never saw a Dolomite in the U.S.

Question 3. A two part answer. Part One: NO with regards to a Midget unless the Midget has a factory installed 1500cc engine (that engine and gearbox are Spitfire units). Part Two: Through my experience, the gearbox as used in the Marina has a longer input shaft than a Spitfire; perhaps taking parts from the Marina and rebuilding Spitfire gearbox might work but it may have different ratios. Otherwise, the answer is NO.
