Great news - got my new air inlet housing delivered from the USA yesterday and the part is the same as my broken gear! 😊
The recirc door looks the same too, so I may as well use it also. The plastic gears with the new part are black and seem much more sturdy. Now to put the whole thing back together!...
The LHD housing goes into the bin now, but better than spending ~$140 and having to turf the whole thing!
