a regular commercial
extended seat but discovered that the holes for the seat bolts were not the same width. So, I can't use a regular toilet seat.
I checked the Jabsco website but could not find any other options. Does anyone know a supplier that makes larger seats? Or am I just going to have to build my own?
How about an adapter plate (the plate bolts to the existing holes, and the new seat bolts to the plate). Make it out of 1/4" aluminum
. Then you can use any seat, easy as can be. You could even sit the larger seat back a fraction, to avoid too much overhang in the front. Yes, this will mean the back is 1/4-inch higher than the front, but this is not really noticeable (been there, done that).
You will need to install the side-to-side stops under the new seat, to control side load when heeling.
