which axle setup?

[chigger]

Can't help you on this one. I am not familar with the turbo suspension arms. Most likely the axles which came with the turbo arms are the ones you need to use. The 944 trans is about the same width as the bug I think. If you change the arms the axles which came with the arms should be the right length.
If the axles don't bind at level or full down they will work. What happens if the axles are to short is that they will pull out the center of the CV at full down or up. If they are too long they will push out the center of the CV at level. If the axles are OK you can grab them and move them back and forth with the car level. Depending on the condition of the car this may be easy or hard, but if right they will move. Hope it helps.
