Swing Coupler for Trailer

[cbart14]

Guys,
Just got a new pontoon trailer (Wolverine)...Won't fit in garage. Looked into a swing coupler and found the one by Fulton (and others)...Problem is that my tounge is a 4" X 2" version. Every swing kit I can find is either 3" X 3" or 3" X 4", etc. Anyone know of one that will fit mine?

Thanks

Any welding shop in town can certainly fabricate one for you. Here is a picture of how Shorelander does it.

Looks like that's the route I'm going to have to go, not having much luck going the DIY route. Thanks for the pic!
