Well, I finally found a company to make me some wheel spacers for my 3rd Gen wheels. If you've seen my pics you can tell they look kind of odd thanks to the lack of backspacing. Here's the specs for guys that are trying to fit the 3rd gen wheels:
Bolt Pattern: 8x165.1mm (6.5")
Stock SRW Studs: 1/2"x20
Hub diameter: 121.3mm
Mine are being made at Motorsport Technology in Ca

The website is real handy. Has a form to fill out for all your measurements so you can price them out online. They make one- or two-piece adapters/spacers and can make them cut to the size of your hub and rim. They'll pretty much make them as thick as you want with pretty much any stud. You really only need about 1/8" or so to clear the rims but like I said even with 13.5" wide tires mine are still stuffed completely in the wheel wells so I went with 1.77".
