I started this topic from the point of view of Dan Walters article on Installing a T5 with no cutting, on the Tigers United website. Dans article alludes to the AMC tailshaft having the shifter near enough in the right position. Then I spotted this TVR tranny whick looks like it matches up. I will try to get some dimensions. I just hope TVR took the Mustang style input/output shafts with the correct lengths, splines and diameters; a Cosworth one would be no use to me.
I will ask the vendor to check those for me, but I am quite hopeful as the TVR Speed 6 engine has a high torque and horspower ratings similar to the V8 engines.
