I am replacing the front and back bumpers on my 1st gen Durango with some heavy duty aftermarket winch-bumpers. I have never removed bumpers off a vehicle like this and am looking for tips/tricks to getting them off in good condition (so I can re-sell them) Any advice is most appreciated! I looked for institutional videos on this and could not find any. I am sure it is somewhat "straight forward", but I am also sure there are some tricks to getting them off as well. Thank a bunch!
