Overdrive identification

[kin74]

I found this overdrive in a spare box, could anybody guess which car is it for?

J'Type - 1500 Spitfire if its OE. Can also be fitted to late GT6  or with people mixing and matching bits Herald & Vitesse.

ps change the adapter and the mainshaft and you can fit it to a 3-rail gearbox. (J'Type is stronger than D'Type)

It does look like a job type with the adapter and mainshaft to suit a Spitfire/single rail box.

Thank for your replies.

So, theoretically, could I adapt it to my Spitfire Mk2? I wonder how much work and how many parts I would need and if it's worth it.

[Richard B]

Personally I would say get a D'Type, unless you have significantly more power than a OE 1147 Spitfire engine.

Standard 1147cc engine.

I wasn't even look for an overdrive and I'm afraid the proper D type would be hard to find and expensive to buy. I just happen to have this J type in my box and wonder if I could use it but it probably requires lots of parts and work.

I expect you can find someone or some company happy to swap a D-type for that as for many applications the J-type would be considered superior.

Obviously you'd need the correct adaptor plate and mainshaft too.
