Modifications weren't too bad, I only had to modify the front brackets. I have the boards about and inch off the body, I can just get my finger between the board and the body.
On the bracket that attaches to the outer body I slotted the hole about another bolts width on the bottom:
On the board itself I trimmed the lip away were the front bracket sits so I could slide it farther back, I used a die grinder:
Other than that I have been very happy with the boards.
