Restoring old Schuco model cars

[Ayahuasca]

Having a clear out and found my old 1970s vintage Schuco model Matra Ford and Ferrari 320PS.

Would like to restore them if at all possible. Anyone know if bits are obtainable?

I think your best bet is eBay, and scavenging spares from similar models with the bits you want (it's what I do).
