We can provide the invoice, packing list and CoO for any order.

Is there anything I need to know before installing this part?
Worth knowing first: Clean both mating surfaces and apply the specified sealant in the recommended pattern.
Is the genuine part worth it compared with an aftermarket equivalent?
The genuine part differs in ways that show up in service: the number is confirmed against the official Toyota catalog, so the application is exactly right for your chassis, and the part is verified against the OE number before dispatch, so you receive exactly what your chassis requires. These are the aftermarket equivalents you may also see quoted.
