my 1998 Safari came with an odd size bayonet waste termination. I received an adapter (manufactured by M&M) from the previous owner which reduced the outlet flange (3.75" OD) to a more common size of 3.5" OD. One of the flanges just just broke. I have searched and can't find a replacement. Any ideas where I can find one? or do I need to cut off the current one and epoxy in a regular connection?
