Hello folks could somebody just answer a quick question for me please.

I'm off to look at a Z31 for somebody as he is away and wants to get his GAZ coilovers made up while he was away. Now I understand they require the front struts stripped down and sent to them. They don't need anything from the rear do they? Also the fronts from my understanding its hub and brakes off to get the strut off. What size is the hub nut before I go and check it out as well?

Thanks folks

Marty
