Just curious.
I guess I'm also now waiting to see what length difference there is between my new TKO600 and the old T5 box in terms of my driveshaft too!!

Thanks for your interest Steve,
The situation with the 6L80E Tiptronic is that it has a really short yoke. The original yoke has a tapered flange which fits precisely over taper on the main gearbox shaft. I couldn't use the original yoke or flexible rubber coupling because of the difference between the angle which exists between the diff and the rear oif the gearbox. The original yoke could only be used if the angle was 1 degree or less, otherwise the power that will be transmitted through this system in my Cobra would rip the coupling to pieces. The actual angle between the diff and the rear of the transmission on my car is about 15 degrees.
In my other car, which is a current model HSV Grange and it is fitted with the same engine and gearbox as my Cobra:- An LS2 307 kw V8 and 6L80E Tiptronic transmission, the slip yoke slides up and down the shaft as the diff and gearbox are in perfect alignment. Unfortunately, this is not the case with the Cobra. The gearbox and diff aren't in alignment.
To overcome this problem, Metropolitan Drive Shafts constructed the hydraulic ram on the tail shaft to compensate for the required movement under acceleration.
Hope this explains the situation adequately.
Baz.
