Peace be upon you. I have spare parts for a Camry 2011. Starting with the original alternator, it's from the agency but it's broken and needs new brushes, which costs about 100 SAR. I also have a used original belt tensioner, it's in good condition. And I have an original gear mount that needs a new bushing.
The alternator is 50 SAR, the gear mount is 50 SAR, and the tensioner is 50 SAR. If you want them all, it's 120 SAR.
