Which CV Boot?

I'm hoping someone can point me in the right direction. I have a split CV boot on the LH side, gearbox side of the shaft. Every website i look on has many different sizes. My car is a 1991 cab, 1.8 112bhp (LHD). I've measured the diameter of the shaft and its 27mm. On the websites i have a choice of diameters 35mm or 22mm! Anyone got any ideas?

Thanks

Give these people a call, I'm sure they will be able to help.

Brilliant thanks for that Mark!

mk2 golf gti is what you want if that helps, you have late cab 100mm shafts with mk2 cv joints on

Ah that would explain why its so difficult to find the correct one under "MK1".

Thanks a lot John!

Do you think this would be the correct one?

possibly, but way overpriced!
