• Fitment lists are a guide rather than a guarantee, because the same model year can carry different parts depending on the production break and the option code.
• Electrical and fuel-system parts are normally excluded from return once fitted, since they cannot be resold as new after use.
• Superseded numbers are common, and where a factory number has been replaced the current part is usually dimensionally identical to the original.

Where a component shares an earth with others, a corroded earth strap produces faults that move around as loads switch on and off. Genuine parts are made to the drawing the vehicle was built from, so dimensions and materials match the part being removed rather than being close to it.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Handed to the carrier within one to two business days from our US warehouse, free over $59.
