Are you sure that it was a GT-6 gearset, ie not spit internals?

Since the GT6 gearbox has a different gearset than the Spitfire has, I can'=

a ratio of 3.75 compared to 2.65 for the GT6, therefore the input shaft ge=

It is my understanding that you can have the GT6 input shaft either machine=
d to fit or you can cut the input shafts from a GT6 and a Spitfire and weld=
the Spitfire on the GT6 transmission.
