The Lightning bolt pattern is supposed to be 5 x 135 mm,right? Well I divided 135mm by 24.5 mm,which is supposed to be a inch,and I get 5.51 inches. That's 5.5 inches to me. Am I missing something or what??

25.4 not 24.5

 

So that's what it is. The book that has my formula's in it says 24.5. I knew something had to be wrong. Thanks for the info.
