Got the swing tongue and frame cracks fixed. Cost to do away with the failed $500 dollar option...$300. The fix was as follows.
The cross piece that makes up the swing portion a frame with coupler was taken off, separated, squared up and re-welded plus angle brace added. The pivot point was ground off and a side plate welded to the frame. A plate of the same size was welded to the curb side and gusset added to the bottom on the curb side. All cracks ground and welded. The tongue now travels parallel to the ground even without the WDH. Tongue jack is now at right angle to the frame when supporting the tongue.
