This probably doesn’t help you a lot Terry, but here goes. I wanted to renew those bits on my D. I scoured the internet and found a DZUS catalogue, whereby I could find the clips, and all the other hardware. Part numbers the lot. All I had to do was find a supplier. I did find one in the US and asked for a quote and do they ship to Aus? Yes they did ship here but I had to buy something like 1000 or 10,000 or something ridiculous. That ended that enquiry. They did note some other suppliers in the US, all racecar shops or the like. I haven’t pursued that any further.
