Hi 12B. My 65 stang oringally had 4 lug wheels, hub caps. I had it converted to 5 x lug 15" x 7", 5 x 4.5 bolt pattern Cragars and BF Goodrich T/A's. I didn't know at the time, but the wheel shop put in spacers on the front inside wheels. The rear end axle was from some other car and did not need spacers. I had 225 60 R15s. I should of put in 220's as Tim suggests in the previous post. In Australia, where I was driving my Stang for 3 years, I was informed that it is against the law to have spacers for their safety specs, so I got a hold of 68-69 Mustang slotted wheels. Last month I went to Coker tire and got the 1965 SS style wheels and BF Goodrich T/A's again. Anyway, I digress. Have you contacted Cragar directly or gone to their website? I have a pic with the Cragars on, but I haven't figured how to attach it to this reply. I loved those Cragars on my ride. They will look so cool on your Stang! Jetsetmantony
