pretty simple un do your pegs and add what you want. If the new peg does not have metric threads you have to add adapter.
If you do ones that have a straight threw bolt go to hardware store and buy longer metric bolt. Harley pegs will work with that adapter look at dennis kirk they have 300 to chose from
