What bolt pattern

[Shamrock--WV2NC]

I have a 74 Dart Swinger originally a 318. It has 15x7 police wheels on it now. Not sure bolt pattern.
I searched bolt pattern trying to figure out how to measure to see what bolt pattern I have. I got a bunch of results but not what I was looking for. Can someone post a diagram or pic of how to measure.
I drive my car everyday and really should have a spare in the trunk.
Thanks

With one lug studs at the top. Measure from the center of the lug stud at 10:00 to the outside of the lug stud at 2:00.

It won't measure exactly 4" or 4.5" but will be obvious

If they're really police wheels then they're 5x4.5", police wheels only came in the "big" bolt pattern.

Here's a diagram of how to measure though

Thanks. I just measured it’s 5x4.5.

Does it have disk brakes? If so, it'll be 4.5" B.C. That started in '73. AFAIK, '73-'76 with fr. drums stayed 4" til the end

Yes. It has disk brakes

Yes. It has disk brakes

Disk brake cars went big bolt pattern in '73.

The 15" cop wheels never came in the small bolt pattern so that kinda narrows it down just a little bit.

Problem is, there are after market wheels that copy the factory "style", that may or may not be identical to the factory dimensions. I have a set of "rally" wheels. The front are 14 inch 5.5 wide with a 5 on 4 inch bolt pattern. The rear are 15 inch 7 inch wide with the 5 on 4 inch bolt bolt pattern.

No reproduction cop wheels in SBP either.
