H1 Parts Catalog

[DiscoDuck]

I have tried a search but don't seem to be finding any good information....
I am looking for a parts catalog (online) to help me replace parts as required on my 98 H1 that I just bought.

Does such a beast exist? Where?

I currently need to resolve:
The button that controls the side mirrors broke off and I don't know where to get a replacement other than the local dealership but they want too much for everything.


Thanks
Shawn
