Hi guys:I am upgrading several parts of my 1990 Hunter 37 which I recently purchased.1). Dome lights, would you replace them with the new mr led ones? low energy comsumption..etc? any suggestions on dome lights?2). the mainsheet halyard (line only) is damaged and need to be replaced as well as the mainsheet cleat located at near the gooseneck which is not operating. Where to find this items? can the cleat be replaced or has to be upgraded to a different version.3). what to use to fix the polyetilene holding tank (new) the the fiberglass bottom? Epoxy puty?4). Need to be hoisted up to the top of the mast to replace the vhf antenna, install a new 360 Deg 2NM hella light, install a navman W3100 wind tranducer and wire it down. I purchased the Professional Bosun's Chair from west marine...how to configure it to be hoisted?Thanks!!!
