Hi guys I wonder if someone could help me please? I'm not from the states so hopefully we all call most of the parts the same thing.

I have a 1995 Audi 80 TDI. The cv joint has just collapsed and I need to replace it. Apparently there's a few different types of cv joint so I need to count the splines on the driveshaft both inner (from gearbox) to the outer (at the wheel). I like to have all the parts ready for fitting rather than take it apart and then drive to the parts shop so does anyone know how many splines there are for this particular model?
