New to this site. I am in process of restoring a 85 340EC. Looking to remove the cracked dark grey acrylic panel that is aft of the dinette and forward of the head. It would appear to be adhered to the wall with mastic (?). Has anyone tackled this project? I think that you have to remove the tambour section just to the rear of the folding dinette seat to gain access to the panel. Any ideas? Thanks.
