I can't comment on fenders from that particular vendor, but I have two new aftermarket front fenders on my 1984 F150. They were purchased locally, and they were the best ones I could get (well, the most expensive ones, which we had hoped meant that they were the "best"...lol).
The passenger side fits better than the driver's side. Overall they are not bad, but the driver's side one doesn't fit perfectly with the front corner of the hood. It bugs me, but I don't think most people would notice it. Otherwise it lines up decently with the hood, the door, and the A-pillar.
I don't know what brand they are, but they had decals on the backside that said "CK" or "GK"?...lol.
