We had exactly the same cluster in our T4 managed to get a replacement from Cali Campers but that was 2 years ago at least. We used a guy off Facebook called Loom Wizard who supplied and fitted updated Blue clocks that are still working perfectly ( see our old T4 around locally).
The clocks we got from Cali Campers we sold on again after having the Blue clocks fitted.
Best of luck trying to find them but it was a straight forward update to the Blue clocks and looked loads better too.
