Fits like a glove. I'm not sure how this person can sell them so cheap, but they look and feel like standard Ford locking hubs have been pre-lubed. Be careful when inserting, don't force them, just twist them until they go in with minimal effort. The old ones I had were still in decent condition, but a couple of the plastic pieces that were inside closer to the outside had broken off and were swimming in grease in the hub. So I swapped them out just in case since I also swapped out the front…
