Best case, the screws are lagged in. Remove screw and epoxy
fill the hole. Drill new pilot, bed
with butal and place new track... DONE
Good case, bolts have fiberglassed in nuts, follow directions as above. NOTE, remove screws by hand. DO NOT USE A POWER TOOL.
Worst Case, nuts are loose and you cannot remove the bolts with out loosing the nut. Remove cabin
liner and try and get to the deck
joint. This will take alot if time. You will probably not be able to save the lapstrake cabin
liner so just tip it out and replace new. One out you should be able to reach the deck
joint and backing nut. Remove and replace as per above.
