Ebay Germany and Austria normally has a lot of parts for this model and they are more often that not in very good condition and not totally stuffed like you see elsewhere. I bought 2 sets of excellent DR forks last year. One 82/83 set from Austria and one 84 set from UK which are very rare as they have the updated sliders with internal bushing and PE style wiper seals and was only on the 84 and newer DR500S. Both were quite expensive to import but to me it was worth it when the chrome on both was perfect and the sliders were not all beaten up with gouges and gravel rash.
