Um, call your local wheel and tire shops? I just called around to a few and found one that sounded like they didn't have their heads in their asses and took my stuff there. You can ask to watch too, if they say no then go somewhere else. I bull****ted with the installer of mine for like 45 minutes about Mustangs and street rods.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
