Anyone have ideas on a replacement lid gasket?  Seems as though only the 55 gasket is reproduced.  I know the 85s aren't as popular since they are larger, but for those that have restored them, what do you use for a new gasket?  Do you piece together two 55 gaskets?
Also, I took the lid apart and under the top lid there is particle board and then insulation on the inside lid.  Having particle board under lid seems a strange chose (as it holds water).  What do others use under the lid when restoring?  Plywood?  Would spraying it with bedliner help?
