I have a older craftsman garden tractor about 16-18 years old.It is a 46 in. deck I do not have. I do have a craftsman lt 1000 deck from about the same year, it is a 42in. deck. Looking at the book thay kind of look the same. can this work or do I need to find a deck for the gt?. if so how do I go about finding a belt to fit it? Thanks for all the help, David
