Sorry, guys - no time for the moment to develop a small lot of the turn signals. Perhaps in spring?
But before you are throwing too much money against your screens, I'll give you a small hint regarding the exhaust tips: it seems to be no good time to get good used ones here in Germany. But perhaps you guys have better luck?
The basis parts are coming from the Audi Q7 4.2 (pre LCI).
There are different types available - you have to search for the exhaust parts, where the tips are welded together with the inner pipes. Outer diameter of the tips is 100 mm.
You have to grind, to cut and re-weld the inner pipes with the outer tips to the desired dimensions.

Grinded and first cuts:
Cut to lenghts before re-welding and installing to the car:
Good luck!
If you have further questions, please write me a pn.
