You have the answer for correcting LOP if needed. You bought it used, so perhaps you won't take a beating selling it used. Get the SBE II and you get shims and the ability to add different thickness of pads.
Many have a poor mount and if corrected could go longer. However, if one already has a good forward or leading hand move and point, then a little short beats a little long every day. Adding extra clothes during hunting seasons makes a little long now more of a problem later.
Addition: Good chance the SBE II shims will work with the SBE I if the receiver/stock mating isn't drastically different. You can make a cut up credit card work also. All they do is up, down, right, left.
