Hi George,
At the moment the rear suspension is in a state of flux. I'm planning on something a little more radical but that might not work i which case I'll have to use the struts I took off the car. The wishbones I took off are alas burgered, the actual hub/strut isn't much better to be totally honest. So really I'd suggest a quiet word in the direction of Peter Mac or Rob Hughes. Try and get 260Z rear wishbones though as they're a bit tougher than the 240Z ones, exact same fit though.
Cheers,
Rob
