For the side rail bolts the correct dimensions are 10mm head, 6mm x 20 mm shaft but for the bolts that go down toward the fender, on my bike the 10mm heads are too small. Is it possible Phurp was referring to the fender bolts being 13 mm heads, 8mm x 20mm with a 1.25 pitch??? I'll try it out today.
Use blue thread lock!
Yup: 10mm head, 6mm x 20mm shaft bolts with a 1.00 pitch hold the luggage rack to the sides of the sissy bar. You need four of them. 13mm heads, 8mm x 20mm with a 1.25 pitch for the bolts that insert towards the fender. You need two of these.
