A few weeks back I was asking about the "earlier, thinner" front bumper shackle mounts.......and someone did confirm that they exist. Well, I found a set. It was unintentional, as a guy on Ebay was selling a lot of parts and these were in that lot. As was stated earlier the older mounts have a thinner base, which you can easily see in the pics. They also have less "meat" around the bolt holes, which you can't see from these views. That makes them a bit smaller width-wise. Interesting stuff......I just thought you guys might like to see the differences.
