01E axle info

So, I've been doing a bit of research on the appropriate axles to use on the Audi 01E fwd 6 spd transmission. I'm curious what everyone else used for the axles. I know the cups are 108mm, but thats about all the good info i've been able to find. I'm looking for specifics on cup bolts, spline size and length particularly or even just donor car info. I'll be needing to splice all of this to my existing lotus axles. So I really only need the info for the 01E transmission side of things.
Any help would be greatly appreciated!
You will need 100mm cv joints which have a pcd of 86mm, you should be able to find these with splines to fit your existing drive shafts but you will likely have to get new shafts made to correct length.
