[Fot] Spitfire Gearbox

[Brad Eells]

Interesting...I received three gearboxes with my Spitfire. 

In the car is an overdrive box. The other two are standard 4 speed Spitfire boxes; one labeled ‘wide’, the other ‘close’.

Now you have me wondering what’s inside??

How did they build different ratio boxes back in the day?

This year after the Kastner Cup, Marty Sukey suggested finding at GT6 gearbox as they have a closer ratio gear set - I think I even remember reading that some of the LeMans Spitfires had GT6 gearboxes. I'm having a difficult time finding one so I was going to ask the folks that have been this a lot longer than me, is it possible to just put GT6 gears (specifically 2nd and 3rd) into a 1500 Spit gearbox? Has anyone tried? Are there better options? I have two extra 1500 single rail boxes to mess with. Any help would be appreciated. Thanks!
