I went to check when my VX was manufactured, and it was back in March of 99. I have one lugnut that is different from my others, and it came off a Rodeo, but I have no idea what year that vehicle was. Since posting the question and following links provided by you good folks, it seems like the 12mm x 1.5 is pretty standard on all Isuzu models. I will try calling my local dealership to see if someone can look it up, but I'm sure my question has been answered. Thanks.

As far as any info on the Meet in Vegas, let me know, and I will try to offer any information that I can. You can e-mail me at j.lamps@lycos.com
