1999 Wide Glide, Sorry I haven't been on this forum for a few months. Your fender width should be a fairly common one at 7" or just over it. Best thing to do is measure your stut width and use the narrowest point (usually the rear ends) and order a sheet metal fender that is around .5" or less narrower, the sheet metal will pull out when tightening to the struts much like your current fender. Don't get it exactly the same cause it will scrap when you slide it in. Klock Werks makes a nice fender that is stretch for the softail that (I believe) is 7.125" wide, but its a little pricey.
As for the bags, there is a web sifte that has them cheap, check out the Dyna forum and look in the bagger mods threads, its either this one

https://www.hdforums.com/forum/dyna-...onversion.html either way you will have to fab your own brackets and depending on how you want them to fit behind the shocks or over the shock you might need to do som e fab work to the bags.
