I have a 50-year-old Triumph Herald convertible which has had problems with door closure needing a really hard slam. I took the door seal off and it closed nicely but left a big gap obviously. I searched for door seal and found carbuilder.com and looked for a thinner version of seal. They were kind enough to send 6 different samples to try and I now have doors which close like they were when new and much quieter.
