I bought the Pat's when I bought my tractor. I did end up buying a longer top link due to the additional length the Pat's adds. I'm actually very glad I did though. The new top link was like $30 and is a much better and way more easy to adjust top link than what came on the tractor originally. I have all my attachments set at the same widths for the lift arms and I find it so simple to change implements by myself. 94BULLITT mentions something to hold the lift arms in place. I'm not sure what that is, because I don't have that and apparently don't need that. Maybe some do and some don't.
