Yeah, only now I can't find the link anymore. Had it a couple of days ago. Thought it was edmunds but now not sure. Will have to comb through my recent links and bookmarks.
It was late at night, my family has two machines, and I sometimes work under one of the other people's login, or under the admin login, so it could be stored in any one of eight places. Didn't need it at the time, because I was planning on staying with the 15x6.5 steel wheels I have on my 97 GM.
When and if I can find it again, I will post the direct link.
Sorry bout that, try to be more careful next time.
