I have a R-62 that I bought with just the standard stone door. The first day out with it as you might well guess, I stuffed a rock in it. Come to find out it didn't have the rock bar across the door and it bent things up pretty bad, the dealer came down and we had to pull the rotor to straighten things out. Soon after I read about the stone trap and ordered the kit and I could not be happier. I never have get out of the cab to close that stinking door, or smash my fingers with those two darn levers. I must admit the fellow in a post earlier said the trap should be cleaned quite often, every two or three days seems adequate, I sure do like not worrying about whether the door spring was adjusted to tight and you don't have slugs opening it. I too would like to know about the pvc pipe trick! Thanks, and I hope I have given you some good food for thought. Dale SC MI.
