Please research what SE Beadlocks are going for, let alone just the standard stock beadlocks. You will be amazed in comparison.
Actually just to help out. Standard stock wheels typically can be had for $500 or less. You will be lucky to find a set of SE for twice that (I've only seen it for sale ONE time at that price (and it was a mistake)). Typically you see them for over $2000 for a used set. Retail from Ford is somewhere in the neighborhood of $1000 for each wheel. I know it's crazy.
Regardless, good luck on your search and if you get them, you did a great job. Kudos.
