HELP - Need a Bay bucket seat 77-79

Bit of a long shot but ideally I need a driver's seat base from a 77-79 Bay Kombi. Really just need some springs to repair a customer's seat base, so it doesn't need to be in great nik.
A passenger seat or seat base would do the trick as a donor for springs, but if someone has a good seat that'd be brilliant. Same as the one in the pics.

Thanks
