That's exactly the kind of information I've been looking for.
To answer your question . . . I haven't done it . . . not yet. I have my struts/springs that will be installed, but I haven't found what I've been looking for.
For example, I think the stock pieces are too costly, and I'm looking for the Nissan part numbers that reference the same OEM piece that can be found with the Infiniti part numbers. Right now my concentration is on the control arm, and I will find out in a few days whether or not the SE-R motor mount insert for the rear mount will fit the G . . .
I'm not going to stop there . . . even if the mount from an SE-R isn't the same, there's something in the Nissan stable that matches . . . could be an Axxess, or a Pulsar, even a Stanza for all I care, but I want to find it.
Sounds like your forming a solid suspension . . . what're your goals?
