The product is sent as disassembled and there is no mount/assembly guide provided with the product. I will update when I mount the it to the car.Edit: When I contact with the seller, they provide a one page pdf which is not a complete assembly guide. It needs to be updated. But there is no explanation in the product description that it will he shipped as disassembled. Prodcut is solid, should be good quality. I am assembling it according to the product photos here.
