I called five different places and I am out of luck. The spindle is welded to the upright on my trailer, so it would need to be cut off because it’s destroyed. All of them told me the trailer was too old and it would need a custom axle made for it. Even the trailer manufacturer said sorry.
I ended up ordering a new trailer for it. The problem is that the new one has an 8 week lead time and the boat is stuck in the water. The people at the park are having a cow about it being there and the trailer sitting there with one tire on it in their lot. I had to do an insurance claim for it. Because it’s so old, they won’t completely cover the cost of the new one, but will pay to have the boat transported to the dealer for dry storage until the new trailer arrives. Oh well, shit happens.
