I found a different solution, but I did experience the exact same thing with the lite ply plates delaminating. What I ended up doing was putting 4 screws in each plate from the bottom into the hardwood gear block. I used some old sheet metal screws I had lying around, they were about the size of a 2-56 screw, a half inch long. I pre-drilled with a 1/16th inch drill bit, and put in the 4 screws on each side. We have a grass field here, and it's under development, so it's still pretty rough. I didn't have any more landing gear problems, and I didn't have to worry about messing with retracts.
