Getting the A-frame in A+ shape

My brother-in-law is working on getting the A-frame in better shape.  He didn't like the way the hitch looked bent and as he's been grinding off the pieces, it appears that it was quite a welding mish-mash.  It will be nice to have it cleaned up and welded properly.  In these before and after photos, the coupler hasn't been welded on yet, but it fits perfectly.
