bolt pattern?

[cr 57custom]

I am purchasing a set of rims and my car is in storage so i cant meausure. I have a 57 custom 300 and the guy on the other end of the phone cannot find my car lol. Of coarse they are five bolt but do you know if they are 5 on 4and a half are what are they? Im pretty sure all late model fords are the same but I dont want to buy a set of wheels that will not fit come spring. thanks
