If anybody's looking for a set of fiberglass wheel arches, I've got a set that I'll "give" you. These are Mini Mania/Mini Spares part # MS128. Info is here:
http://www.minimania.com/part/MS128/Austin-Mini-Group-5-Arch-Narrow-3-Inch-Budget-Type-FlaresThese arches are brand new and have never been trimmed, drilled or installed. They were given to me a few years ago but I can't use them on my car because I've radiused the wheel wells about an inch-and-a-half to accommodate my big 13-inch slicks.
They have a white gelcoat finish and no cracks or dings but they are shop-soiled and have some tape residue on them. A good bath and some mineral spirits to remove the tape residue and they should be just fine. With a light sanding, they can be primed and painted to match or contrast with the color of your car.
You can pick them up for free in Shreveport, LA, or I can ship them to you if you'll pay the shipping and handling.
