I found an online aftermarket parts catalog in pdf format. It seems to contain most of the HD parts but it does not have the HD parts numbers or price list. The catalog is at vtwinmfg but do not view it unless you have a couple hours, and a couple thousand dollars, to spare. The good thing about this catalog is that you can save it to disk, and it contains plenty of images.
Are they any other pdf parts catalogs available? Especially ones that list the HD part numbers or prices?
Great link! I still would HIGHLY recommend that anyone who owns a Harley get both the Service Manual for your specific year AND the Parts Manual (again for your year). Both are amazing resources, and you can find them at JP Cycles or other websites, including eBay.
