Hello. Which bolts is it you mean? The front mounting uses the standard footrest bracket bolts with a spacer to fit on the front ones.
The only other bolts are we’re the bracket fits under the grabrail, and on mine they looked like the standard grab rail bolts. There is a bolt each side where the rail bolts to the bracket, shown fitted in the photo’s.I never fitted the rack to the bike originally so not aware of any different bolts required.
Cheers.
