Yeah, don't count on getting them. I have a friend who did the exact thing, he ordered 5, they sent 4 WE beadlocks, told him the 5th was on the way just sitting in a container right offshore during the dock strike and as soon as the strike was over, they would ship him the last one. During the time when it was supposed to ship and the dock strike ended, somehow the rim model mysteriously got discontinued and he could not get the matching 5th rim.
He was pissed off enough after looking for a long time that he sold the WE's and went with 5 matching bead locks from elsewhere.
