If this trailer fits and works for your girl, I had a set of these made for my trailer. Know matter what angle she is to the trailer, she will always end up where she needs to be. The mounts are made to be bolted on. The square tubing slides over a peg, and then the PVC pipe over the tubing. I put the tubing and PVC pipes on when retrieving and remove them when trailering. (I think they look tacky when trailering and take away from the looks of my girl. IMO).
I researched on line, and compared to what I have, they are junk, you will need something strong, if you would elect to go this route. And it will be a whole lot cheaper then a new trailer. I believe my was around $300
