"top & bottom spring gaiters & cat heat shields to be fitted"
I would say these are optional and one of the best things about owning a Morgan, especially a Traditional (or as the factory now calls them: Classic) Morgan, is that you can fettle them and modify them to whatever level you want. Some of the changes will be to suit the way the owner wants to use the car (handling, all weather protection, track days mods, etc) and some will be purely cosmetic: badge bars, aero screens, etc (or cosmetic/functional - for instance: luggage racks, spotlights and bonnet straps).
I'm sure Frank will be a long to explain the reason for his mods and others, such as '1560' will be happy to detail the reasons for theirs (in 1560s case, he is chasing and using more performance - better brakes, tighter handling and more power - predominantly for track use).
