1955 Plymouth bolt pattern?

Does anyone know what the original bolt pattern was on a 1955 plymouth plaza, like 5" on 5", ect. Thanks, xhotrodder

 

Should be 5x4.5.

 

5 on 4.5 and the lugs are left and right hand thread.

 

Yes, 5 on 4.5 is correct. Also keep in mind that the center hub hole is bigger than the Fords of the era, so you can put a Mopar wheel on a Ford but not the other way around. I found that out with my '55 Dodge.

 

Thanks guys.

 

Also, Imperials are 5 on 5, so those pretty Imp wire wheels will not bolt up.
