self drilling screw #6 work great and yes, I put a drop of blue loctite on them. loctite also come in a paste stick now (like chapstick) it works great too.BG-Pete said:Hey Dan...as you can tell by all my questions, I'm new to all this. Your link says to attach the bracket to the swing arm using self tapping screws (not supplied). What size/kind of screws do you recommend? Also, would you recommend using lock tight or something similar? Horn should be here any day now. I just want to be ready.
