[Healeys] Source for Tonneau Zip

[Josef.Eckert at t-systems.com]

 Dear friends,
I am looking for a source to get the original like brass/metal tonneau
zips. Think they should be 32 inches long. Here in Germany/Europe?
tonneau zips are no more available with metal teeth, only obtainable in
plastic which is not authentic. Do you know of a source where I can
order the right metal zips.
Thanks for any ideas.
