I bought the rubber grips on the right side on eBay…
New Main Front Right Grip Rubber and Back Holding Rear Grip For Canon EOS 550D
…while, the rubber that repairs the lower left corner is not available online but is not even supplied by Canon!?
In fact, the Milan Service Center declares that it was part of the front cover, but it is no longer available!?
These parts come off because the rubber is deformed and it is outrageous that the Canon does not want to adequately support its customers!
