I was able to remove the cockpit bolsters, but not the inside ones. I did not find any screws, and the bolsters appear to be securely fixed to the fiberglass. Any suggestions?
Not sure if this applies, but one way manufacturers attach these is a small slit in the underside of the fabric where you can find the screw head. Another, would be screws from the backside (either top or bottom).
Take a flexible metal or heavy plastic strip, slide behind the bolster and slide it along left to right. You should find a screw hidden in the upholstery.
