Craig - it's a snap to replace the one rubber part at each corner - just need to create a minimal amount of extra space to slip the old ones out and new in - all the attached stuff won't hold it back enuff to be a problem - can almost use a long prybar against the frame [suitably padded w/ wood blocks] - loosen all 4 bolts, remove 1, pry up that corner, replace rubber, slip that bolt back in, go to next
