WTB: Hartal Door Replacement Parts

[kambaku]

I am looking for a source for Hartal door replacement parts, specifically the Hartalux door. http://www.hartal.de/en/produkte/reisemobiltueren/hartalux.html Hartal doors are made in Germany and I have not been able to find a source for parts here in the US. At this point my inquiry to Hartal itself in Germany has not been answered. If anyone knows of a source for Hartal parts I would love to hear from you.

Many thanks...
