Thanks for checking into the tread width on the 300zx rear. Interestingly, the parts on ebay seemed fairly costly for what they had - $300 U.S. "buy it now" price on the center section and axles only. They were from a twin-turbo model and that may make some difference. I still want to look into this further before I go much further on my t-bird IRS.
