I should warn you that you will also more than likly need
these they usually rot like ****.
Also, you'll more than likly find that the body tub rotted where the old wheel house joined it. best method to fix that is to pound out a piece of sheet metal for a patch, hold it up against the tub, mark around it with a silver sharpie (they show up better), then cut smaller than that and grind/file/dremil the hole out to fit the patch, then just weld it up.
here's what i did
one more thing, when cutting the spot welds holding the wheel house, center punch and just drill them all the way through from the top, this leaves you holes to plug weld the new one in, and have the quarter panel in place (even if just tack welded) when you go to put the wheel house on, makes the job really easy.
here is a link for a zip file containing pics of what i did, actually the truck has been ready for paint since mid july now, just haven't gotten it done.
also, to prevent it from rotting again, i used a ton of bedliner on the inside of the quarter, and on top of the wheel house, and the body tub, kinda made welding the quarter to the wheel house impossible so i used 25 stainless sheet metal screws (self drilling), thin nylon washers and tons of seam sealer. a couple of professional body guys that gave me paint estimates said that they'd never seen anybody do that, but that it should work great. You wont see the ***** heads with the chrom trim piece in place that im just going to attach with gobs of high temp RTV silicone (the regular harware store caulk gun silicone breaks down at high temps, and you can burn your hand on a hot car in the summer.
