Ok so about a year ago I had a very bad blowout on my passenger side rear trailer tire (18lt) it was raining and I never heard it blow so I'm sure I drove like that for awhile until I saw to fender was hanging out in the other lane of traffic.
Anyway I cut the excess fender off and replace the tire with my spare. A few weeks later I purchase a new fender and let it sit in the garage as I've had a busy year with a new house and new job. I have a day off and I'm trying to replace and I'm having no luck getting the old fender off.
The blot goes through the fender through the plywood and into a nut pocket on e back side of the plywood. Only about half of the nut pockets are exposed on the back side and every single one of them are spinning. I've shot wd-40 on all that I can get to but I have no idea on how to get the nut pockets that I can't see to stop spinning and remove the old fender.
