I would like to remove the upholster in the cockpit but it looks like the backrest that is directly behind the helm can only be removed unless you dismantle the helm seating platform to get to all the screws.It looks like sea ray attached the back rest before installing it. If anyone has any info would be great.I can get to a lot of the fasteners through the under the front seat compartment and some down through the cup holders but can't get to the end screws around the corner from the arch.
