Well Actually its the outpuy shaft that is different. 23 spline on the 3t rather than then 21 spline on the 2t.
The input side of things is identical.

Spoke to Dattoman1000, and he seems to think that it should all fit.

Kue1000s setup fits nice, so I dont know what I am doing wrong.

have to shift house today, and look at housese for a friend tommrrow, so Sunday, i might get a chance to do something.

I really dont want to chop the tunnel...
