The door to the bath or the frt. door? If the bath door you may have to take some walls out but it should fit out the frt. door.The sink should separate from the shower and toilet, then you should be able to get it out the door. I just disassembled one on a
1964 overlander and I think they are generally the same. They were put together from the rear forward at the factory so you are trying to take out the first thing put in. Hope you get it out without mush more trouble.
