Givi rack help

I have a Givi rack attached to my bike but i am unable to remove it.
1. removed seat and side casings (held on my 4 bolts)
2. undone 4 bolts that hold the rear end of the rack ( these bolts also hold up the the tail lights)

there is now1 bolt each side of final part of the rack, the rack bar runs through the bike and is a couple of feet long. I am unable to get to the bolts, they are the same bolts that hold the rear footpeg plates on. It seems the only way to get to them is to remove the exhaust system. even a socket gets in the way.:frown:

Any thoughts would be appreciated?

 

Sorry, i forgot to mention, i have a 2012 street triple 675
