Question:

do i need to bolt or weld this adapter to the base of my king pin or just tighten the bolts around the king pin. does the mounting screws come with the adapter that goes into the plate, not the king pin. thanks

On the Fifth Wheel to Gooseneck Cushioned Trailer Adapter, # CAB-C5G, you do not have to do any welding or bolting, the collar slides over the king pin and there are set screws that are tightened around the king pin. Then the adapter is screwed to the collar over the king pin. The mounting screws are included.

If you want a semi-permanent application then the adapter can be screwed to the trailer or if you want a permanent application it can be welded to the trailer.
