Hello Troy. The Sealand Toilets were rebranded as Dometic, but I was not able to find any specific reference for the Sealand 340685 you mentioned. We do offer seats for the Dometic Sealand toilets that may work for you. For example we have the Replacement Wooden Toilet Seat # DOM83FR which is made for the Dometic 310 series toiler. The lid is 15-1/4" long overall. I have included more detailed dimensions for you below. I suggest you compare this to your toilet to see if it will fit.
