Morris seat belts

[WSSix]

I need new seat belts to replace the original 34 year old ones. I know people have said they were pleased with Morris Classic Concept belts. What I'm curious about though, is has anyone had them rebuild their belts? I contacted them about color selection and which might match stock best and that's when they commented about rebuilding and rewebbing my original ones. I figure, if the new ones they make are good, then the rebuild service they offer should be as well but I wanted to ask first.

Thanks
