I just bought a boat in so. cal, and am going to pick it up next week. The bow stop rollers are missing one of the rollers, and i'm trying to figure out what to do before picking up.. I know the bow is gonna have a hole in it if i drive back to TX like it is. You can see that the prior genious has the boat set too far back on the trailer. I've looked all over on west marine, and can't seem to find the one replacement roller, as it looks like it's 1/2" diameter pin. I need to drop this in the water with a new bow stop before driving like this. Can anyone help wit an ID on this guy?
