These are the shims I have in my parts drawer. I have had them for a long time but they represent the type of thing that is/was available, by various manufacturers. I think I used one or two under the Moog brand name a couple of decades ago🤔 They can be used to increase or decrease camber.
Me and my wife had a discussion about this earlier this evening before I saw your post. She felt the same way as you. She said if nobody on the forum isn't complaining and I enjoy posting about my Mustang I should continue to do so. I've decide I'm going to keep posting about my Mustang. I've checked with the forum moderator and he says its OK. 🙂
