Frequently Asked Questions: OE 18299121-00
Which side is this arch panel for and how do I check?
Yes, this one is listed for the left side. Before you order, look at the photographs on this page and compare the curve of the panel and the position of the fixing points against the damaged side of your car. Do not go by the word left or right alone, since panels look similar until you hold them against the car. If what you see does not match, this is not the side you need, whatever the title says.
What if the number on my old part does not match this one?
Check the number stamped on the part you are removing before you fit this replacement. This one carries OE number 18299121-00, and if the figures on your old panel differ, do not fit it. Read the number directly off the old part rather than from a receipt or an old listing, since that is the only figure that tells you whether this is the right one. Only order once you are sure the two numbers match exactly.
How does a panel this size get delivered?
The packaging details for this panel are shown on this page. Delivery time is confirmed with your quote. To be sure this is the exact panel your car needs, check it against the alternative reference HA5HA-5401520/70 given on this page alongside the OE number. The shipping cost is confirmed with your quote.
What is this rear arch panel made of?
This is a metal panel, supplied new, for the left rear wheel arch. It carries OE number 18299121-00 and is also listed as HA5HA-5401520/70, so you can match it against the marking on your old panel or the parts book before ordering. Confirm the model and the model year as shown on your registration document against the fitment table on this page before you order, since that is what determines whether this is the correct panel for your car.
