Question
Can an overdrive be added to triumph spitfire i.e. 1977?

Can air conditioning be added to triumph spitfire i.e. 1977?

Can cruise control be added to triumph spitfire i.e. 1977?  

Answer
OD came as an option from the factory; so if you can locate a an OD trans, its a very simple upgrade.

AC could be added, but there is no specific aftermarket kits designed for the spit, so a bit of fabrication will be required.

Some have added cruise via the vacuum kits you can get at JC whitney and the like so it can be done...
