Ok I have had a look at this and if just want to fit a catcher to catch grass and not wanting to keep it original, a Victa catcher from the early eighties to the current models will fit by fitting a piece of angle to the inside of the rear door and that will hold the catcher in place in the same manner the existing catchers are fitted. The catcher will require a small section cut out of it down the front left hand corner, easy to see when you fit the catcher in the throat. Victa catchers are everywhere and are only cost a couple of dollars if you look around. I recently picked up 21 catchers for $20
