Thanks, that seems like the only option left. I had one ordered from Roadtrek but they couldn't fulfill it before going out of business.
Ah bummer, this was the only option I was aware of. You might be ok without cutting down the seat base if that was a concern. I test fit it before I modified the base. It was able to swivel and function fine. My wife is somewhat short and didn’t want her feet dangling when sitting so I cut it down.
Removing the connectors to run the wires through the center bolt was very easy, no special pin extractors needed, just a small flat head screwdriver.
Cutting, modifying, and welding the base was a bit of a pain in the butt.
There was also a side plastic trim piece on inboard of the seat that needed trimmed due to catching on the swivel section.
I’m not sure who mentioned it but adding some white lithium grease in the swivel bearing race is probably a good idea while you have it out!
