沙特阿拉伯采购需求：牵引车，重型卡车，载货卡车，乘龙牵引车，多用途拖拉机，拖拉机供应

I hope this message finds you well. I'm reaching out from Alamuria Company in Saudi Arabia regarding spare parts for Chenglong trucks. We currently operate a fleet of 10 dump trucks and are in need of specific components to ensure their optimal performance. We're keen to know if there are any authorized dealers in Saudi Arabia for these parts, or if you could provide guidance on how to procure them directly. The parts we're looking for include both left and right exterior door handles, an auxiliary water tank, a left-side window regulator assembly, and a controller. Any assistance you can provide on sourcing these items would be greatly appreciated. Looking forward to your prompt response.
