There are vinyl repair guys out there that basically glue and can also paint vinyl if sun damaged. I have found it always best to do repairs right the first time. If they are small splits, the gluing and spraying can work for a little while. But it sounds like you just need to find a good interior guy that will replace the center section or whatever is split. If you can't find the pattern you can press the pattern. Talk to OCCoupe about that. I believe he knows about that. Good luck, curious if anyone has a magic fix but I doubt it if you don't want to cover. Glad you are trying to keep original. Mine were in decent shape minus some minor cracking up at head rest area. I had them "repaired" but they are already splitting, hence save the money there and just do it right. I will have to have some smaller panels/sections replaced now myself. Good luck! Oh, replacing the old horse hair with foam is a great upgrade that didn't cost too much to do. Especially if you are allergic to old horse hair LOL.
