Does anyone know what size the threads are in the middle of the speaker support brackets.I'm looking to mount my crossover plates to them.

 

Should be able to find it here. http://partsfinder.onlinemicrofiche.....asp?make=hdmc

 

If we are talking about the bracket that runs underneath the speaker's and bolts to the lower speaker mounting bolt's.only one hole in the middle They are 10-24 threads. I've got the front fairing off installing 2 inch pullback bars. It's a 2012, but I think the bracket's are the same. I can take a picture if you want.

 

Thanks i'll try a 10-24,i have some.yes that is the one i'm asking about.

 

Are you talking about the bracket shown under the speaker? I have a red pointer on it.

 

yes thats the one.

 

If they are the same, it's 10-24 Good luck!
