I've read on this forum about some installing a 1/4" plate on the outer side of the A-frame and grinding a radius on the bottom to match the radius on the bracket.
I did something like this. I wanted the beefiest possible mount with no modification of the A-Frame. That no modification of the A-Frame requirement created a lot of extra work.
You don't need to be precise so that you match the bracket radius. You are just trying to ensure that the bracket still rests against the trailer frame and not the plate in order to minimize the gap between the plate and the frame. You could also just make the bottom of the plate higher than the bottom of the frame tube.
A plate also provides some insurance.
Rather than put the plate inside the A-Frame, you could also drill slightly larger holes in the frame and weld nuts to a plate that gets welded to the outside of the frame. The nuts would go in those holes.
Many would call this overkill, but I would plate the the inside where the pinch nut goes and both sides of the snap up too.
Also, consider bolting the snap-up. You could use the same approach as with the DC mount.
I think that if you have the DC mount and the snap/ups solidly bolted to the frame that you will have greatly reduced the chance for movement. A plate on the inside of the A-Frame as insurance and snugging up the pinch bolt should do the trick.
You probably don't need to weld a nut on the inside for the pinch bolt.
