I need to remove the side bolster by long lounge seat on Passenger side. I was able to locate 3 nuts and washers by going thru a speaker opening. After removing these, it is still firm in the very forward and aft of the bolster. I removed the side of the area where the battery switch is located, no access there. Cant find a way to access the forward edge, or rear edge. Anybody ever remove this and can give me a little advise?
