Oh and did you sort the shaft out? The more I look at it the more it bugs me... Why does it bolt onto the cross member? Mine is fitted to a bracket where the four holes are in the main rail... There's some blue paint there on yours. If that bracket was there, the shaft you have looks like it would fit?
You're going to have to have a look at that for me, it's driving me nuts looking at it!
sorry Neil, the bracket is there due to it being a long wheel base, youll notice this chassis has more cross tubes than yours

I still havent got those measurement but i will get them for you

"bolted the rubber boot in the foot well"
Where did you get that from a dealer or make it? i could be doing with one of them, theres quite a draft from mine 
The boot was already there, i literally just bolted it down, because it was loose

you could try the dealers though, theyll probably have one lying around from breaking them, theyre quite bad for splitting

and you cant really make them, theyre a very unique shape .
