Thats what I am saying, the description is misleading to the point of being an outright lie!!! Tomohawk is correct... 80 with a core...I used my Datsun cals as a core... the parts dudes never look in the box and if they did, unless it was the same person that sold them to you they are cluless as to what caliper is what...they would be lucky to even know what a caliper is in the first place!!!
It may be dishonest to use the wrong cal as a core but I have had to deal with so many parts "people" that waste my time either giving me the wrong parts, or just being plain useless, that it does not bother me at all. Years ago, when you went to get parts, the person behind the desk was at least somewhat knowlegeable...these days, it is just a bunch kids who's knowlegde is limited to chrome tail pipes and aluminum pedal covers!!!
EDIT: If any of you guys are parts people...obviously there ARE knowledgeable parts people around...just very hard to find. When I do meet one, I remember their name, and then only deal with them at that particular store.
