Anyone know if a sportster 6 hole derby cover will line up with the 3 hole primary bolt holes It looks like the covers are the same diameter so I feel like the holes should line up. Any help appreciated thanks

 

I don't have an answer to your question but how are you going to stop it from leaking from the extra holes IF everything manages to lines up ?

 

It didn't fit but the thought was the extra holes should not leak because the gasket is between the extra holes and the face of the primary cover therefor no fluid would get to the hole
