the side stand looks good to me. Use it. The part that wears out of spec is the hole in the lug, not the pin, so unless you're going to drill the whole thing out to a slightly larger size and get an oversized pin/bolt. I wouldn't worry much about it. If the lug wears out, you buy a new one to bolt up to the plate... that's what I did, after 40 years of use.
If you look at your cradle/swingarm assembly, you see the swingarm tube has a single bolt. That was the deficiency that the kegler clamps correct by eliminating slop between the tube and the swingarm axl. I know that I changed perfectly good swingarm bushings because I thought that they were the problem, when it was the single bolt swingarm tube design which was the cause. I would bet you that your swingarm bushings are fine. I would inspect them and only replace them if they are sloppy.
