You can do the badger fabric door seals, or if you want it this winter, rovers north makes a nice top also with FDS.
Exmor is another possibility or oem bestop which you can get from RN or AB I believe. If you run that long w/o a top the extra 20 minutes to remove the gutter kit is pretty minor.
Defenders don't wear out they just need more parts.
