Has anyone else run into this problem?!?!

I bought new rims off of ebay last week and recieved them yesterday. I brought them to my local tire shop when they put one rim on the front (before tire was mounted), the rim stuck out 1 inch from the fender wall. The add stated that these rims would fit 94 and newer Mustangs. They have a great ebay rating (only one average out of thousands of excellents) so I figured they knew what they had put in their add. The new rims are 18x9 with a 24mm offset. What are some possible solutions if these guys decide to dick me around?
 
I run 18x9.5 with 20 offset, fits under the fender... barely. You'll be fine, your setup is several mm further in than mine, when you have the car raised up, the effective positive camber makes it appear to stick out is my only explanation to your problem.

Good luck!
