I believe there are two kits from John. One for the Volusia with foot pegs and one for the C50 with floorboards. It is fairly straightforward to install. They come with detailed instructions. I'm sure you could handle it yourself. There is nothing complicated about it. It moves the floorboards forward 3" and keeps them at the same angle as the are now.
I have them and it has made a world of difference. So much more comfortable.
I was going to with johns kit,,,,,but his computer was down,,,,ended up with this set,,,,,i really like the fit and look, but they were $300 + shipping.
And can't put on crash bars.....there all easy to install .....took about 30 min.
