No welding is required. The GT6 input needs to be cut to the same length as=
 the Spit. Then the splines need to be machined back to match the length of=
 the Spit as well and you are good to go. It's really quite simple. Don't f=
orget to use my steel/carbon synchro's for the most pleasant shifting exper=
ience. ;-)

It is my understanding that you can have the GT6 input shaft either machine=

 the Spitfire on the GT6 transmission.

Since the GT6 gearbox has a different gearset than the Spitfire has, I can't see how that would work.  The first gear for the 3-rail Spitfire has a ratio of 3.75 compared to 2.65 for the GT6, therefore the input shaft gear won't mesh with the gears in the GT6 box.  Here is a link to the summary of what I did way back in 2000 when I adapted a Mk3 GT6 gearbox to work with a small journal 1296 that I used in my autocross prepared Mk1 Spit:  https://www.geocities.ws/MotorCity/Speedway/1080/gt6boxtospit.html.

If I had a GT6 gearbox, I would compare the input shaft gear with one of the Spit input shafts I have just to see what gives.

This is interesting... As I understand it, the input gear drives the laysha=
ft. Lock the input to the output and you have 1:1 4th gear.  To make a clos=
e ratio box, they could have changed the input-layshaft ratio, in which cas=
e the input shafts would not be interchangeable between the spit and GT6, b=
ut the 1-3 gear sets could be. Alternately they could also use the same inp=
ut-layshaft  gearset and then change the three lower ratio gearsets. In the=
 latter case the input shafts could indeed be interchangeable...
If you look at the 1-3 ratios in Joe's link, the Spit and GT6 ratios do not=
 scale by a fixed factor - indicating it is not simply a change of input-la=
yshaft ratio. This means that the 1-3 gearsets are different, and the input=
-layshaft could be common. Of course it's also possible they changed both t=
he layshaft and the 1-3 ratios..

Thank you,

                      Andrew

I have a GT6 transmission in my spares collection and I have heard they can=
