Exhaust/Bolt question

[ess286]

The other day I noticed one of my pipes was vibrating. I checked and sure enough one of the screws and nuts that mount it to the head was missing. I am off today and want to replace them. Any idea on the size of screw I need? I have an 03 chopper with an S&S 107.

I just installed a set of lock washers that I got from J&P Cycles on my bike don't have the info infront of me but the kit included 4 nuts, 4 half moon shaped washers and 4 snap rings. The nuts go on as normal, then you slip the half moon washer over the nut and secure it with the snap ring. The half moon washer wedges against the pipe and prevents the nut or stud from turning. Part number is 440-583. Price with shipping was 23.73. You can pull it up on line. For some reason other than being an idiot I can't attach the page
