I got mine from Paddock £55.00 for all 4 They are made from fiberglass with a rubber seal strip and I attached them with self tappers and little nuts and bolts. Fitting is easy, but they need a little pulling and pushing to fit right. They will also need a lick of paint. They stick out a couple of inches. I could find some pics if you want.
Rear wheel arches seem easier than front, possibly there's less chance for the wing to be distorted. And the side without the toolbox is easiest. There's a panel protecting the wiring for the rear lights, and you can use that with the self-tapping screws to clamp the extension in place.
Front footwells are damn awkward if they've been patched. You may need longer fixings than you expected.
They don't fill the recess for the door hinge, although the edge crosses it. The front of the sill is also awkward.
Front wheels _have_ to come off to get access for a drill. Rear wheels have more clearance, but still need the wheel clear to properly secure the front lower end.
