Super Pro 190

[Frankj]

I have a 2001 190 SuperPro
I am trying to remove the backrest section of my seat to have it re-upholstered. I was able to remove the storage boxes and access the two thru bolts behind the driver and passenger backrests. Does anyone have any idea on how to remove the middle bolt. There is no way to access it as it is behind the livewell which cannot be removed.
any suggestions would be greatly appreciated.

I had a couple on mine and I finally grabbed the set and jerked it out.
