Im curious on the best way to remove the fenders, specifically how to get them to break free from urethane? Also, what urethane should I use when reinstalling? I assume I can find it locally. I will be adding/welding the support brackets on my 00 trailer to support the new style fenders. Im hoping the front and rear supports match up w/out any modifications required. Any insight or tips on fender replacement is appreciated. Thanks.
