Here's the spacers that I used.
A large washer 1/8" thick on the top mount.
.500 or 1/2" on both sides of the rear loop.
Passenger peg right front .700
Passenger peg right rear 1.565
Passenger peg left side rear .800
I modified the left side front because my boot would catch on it. Keep in mind I wear a 14 boot. Need to get a button head for the front bolt.
You will have to use longer bolts, just add the spacer length to the bolt length. I like the button head, just less to rub on your boot.
Also, the spacers would not be that long if you run the passenger pegs, I just have them removed.
Hope this helps.
