If you have a standard Cold Steel AD10, then these should be a quick swap, just take those liners off and replace with the OG scales, and then the only addition is that tiny pocket clip spacer to make everything look OG!  If you have blade lock up or blade play, then you may have accidentally swapped those pins, as they look very similar but are slightly different and will make a bit difference if installed in the wrong locations!
Now, if you have an AD10-Lite model, you will have to make a small modification to your backspacer to allow your model to accept those beautiful linerless GOATs...there are two small nubs on your backspacer (we believe them to be on both sides as we do not have a lite model currently in-house) that will need to be removed so that those new linerless scales fit flush against that backspacer!
