A while back I came across a great webpage listing the various models and widths of jag irs. I also think it listed one or more that we’re not recommended for hot rods, but can’t seem to find it. It just shows “webpage cannot be found”. Is jh or jhe engineering and Jim still around ?? Or can anyone tell me how to get back to a page like that? Maybe it’s just my internet browsing skills. Thanks, Blair
