Thanks guys, interesting they changed the design.
Must be some lying around somewhere unwanted...
The NOS examples from 340 Onderdelen are rather pricey for what they are, although I guess they are probably fairly hard to find.
Like anything, supply and demand dictates the price....
Certainly, the accessory catalogues are worth a look over, lots of cool options back in the day. Must have been a lot of old stock discarded years ago, and probably some still lying around in dusty parts stores, its just finding the stuff thats the problem!
Cheers
