Are the stock breather bolts on a softail about 2" in thread length, about 5/16 thread, use 7/16 socket to tighten/loosen, have a ball head on them & say 1/8 hole all the way through the centre of them.
I ask this question as thats what my SE stage 1 has at moment and I need stock ones for a SE Heavy Breather I'm thinking of getting.
I found my old stock air cleaner and all the stuff I got back from dealer when removed, but no other bolts of similar appearance to as above.
