Broken dispenser housing

The ice door in this refrigerator was not closing tightly, so I ordered an "Ice Door Kit" to replace. However, when I looked inside the dispenser, I found that the problem was a crack in the part of the dispenser housing that holds the pin for the ice door. It seems that this part (#1 on Dispenser Front parts list) is "Not Serviced" so not available? Any suggestions for best way to repair? Thanks!
