A kit for resiliently attaching a skid plate 10 to a street sweeper S is provided. The skid plate 10 is oriented within a track T between vertical rails R of the street sweeper S. The skid plate 10 is maintained adjacent the track T by a flex bar 40 extending between the rails R and adjacent an outer surface 12 of the skid plate 10. A retainer 60 is mounted to one of the rails R and provides a flex plate 80 which is located adjacent the skid plate 10 and resists skid plate 10 lateral motion away from the sweeper S. The flex bar 40 and retainer 60 are not rigidly mounted to the rails R, but rather are mounted with springs 54, 93, 98 interposed there between to provide for resilient connection between the flex bar 40 and the sweeper S and between the retainer 60 and the sweeper S. When lateral forces are exerted on the skid plate 10, the springs 54, 93, 98 can be compressed and allow the skid plate 10 to be deflected away from the sweeper S without substantial bending of the skid plate 10 being necessary. Hence, the skid plate 10 can deflect when impacting obstacles on the surface being swept without exceeding an elastic limit of materials forming the skid plate 10 and without damage being caused to the skid plate 10.
