Thanks! I noticed some differences in the attach points to the deck (perhaps because it is an older model?), ........... QUOTE]
Different size decks used different sized deck boots. Get the proper deck boot for your deck and don't forget that there is a baffle that goes on the underside of the deck. Don't remember if it is also used on the 54" deck, but I do know that it is used on the 60" deck. I remember Junkman saying that there is also a minor design flaw in the catcher mechanical system, but I don't remember what is was. Possibly you can look for it in the archives, or contact him for more details.
