what do you have now?
a mono seat?
if so you will need to change the bracket thats about all,
to fit a mono seat to a bip frame you need an angled bracket and spacers, assuming you or someone else has already done this, you just need to return it to std with a flat bracket and no spacers ie shorter screws
if you have a bip seat then i dont belive that it will mount on the mono frame
