So when I got my savage, the left rear turn signal mount was broken. I found an OEM replacement on Amazon, and tried to mount it using the screw holding the existing mount to the bike. No dice. The size and/or pitch is wrong. It holds if I screw it in hard enough (which is what the PO had done), but it's clearly the wrong size.

I can't extract the screw on the right side mount to check, as it's rusted and stripped. It's holding, through, so I'm not touching it.

Based on this thread: http://suzukisavage.com/cgi-bin/YaBB.pl?num=1303177039 it seems that I may be looking for a 6mmx1.25 screw, and from what I've seen, that sounds reasonable. However, I have searched high and low, and I cannot find a screw (or bolt) with those dimensions - even on McMaster Carr.  

Does someone know what size I'm really looking for, or if 6x1.25 is correct, where to find one?

Thanks

I pretty much reached the same conclusion as you - "That CAN'T be right!"

I'll probably just end up going back to Lowes and buying one of every possible thread and diameter combination that might be close.

If I remember, I'll report back on what I find. That way, hopefully someone else looking for the same type of info can benefit.

Id bet the bolt in the other side looks JUST like the one you need.. Id be tempted to pull it out & take it with me to the store.. But hey! How often do I have an answer?
