I cut the heads of the hinges off and took the spring out.
While trying to figure out what my next step was, I flipped the bracket/post around to see what that would look like. Well, it seemed to look pretty good. I was thinking that I would need to cut the post off and directly weld it to the pan, but with the bracket still in tact, I knew it would be much more stable. I test fit it on the bike like that and quickly saw that it was going to be just what I needed.
All I had to do was grind some of the paint off and the galvanizing on the seat post (if you don't know...that stuff is extremely bad for when welding). I then welded it up.
Here it is on the bike. It's low, but not so low that the front part of the seat is uncomfortable on your junk. It'll also give me some room to fabricate a license plate mount between the seat and the tire.
