I don't have a pic.
My Jon boat trailer had a broken fender where the the bolt (one of two) hold it to the frame. A few times of the kids climbing into the boat while on the trailer and then pulling it back up to level + time + rust = broke.
I unbolted it, drilled two holes on the other side and put it back on.
Cost + 0.00
PS the two bolts that looked really bad with gunk, and rusty after 10 years of every-so-often being dunked in salt water at the ramp with no rinse came right off with no trouble - Why you ask? - because before I put together any fastener on a boat (or trailer) I use something. In this case cheap marine grease slopped on. The cheap stamped steel (walmart) wheels look fine too if you can see through the caked on grease, dirt, grunge and yuk. HEHE!
OK here is a pic - new camera for Xmas and learning.
