Rick, if you want to know for sure, remove the 6 outer flange bolts and take a look inside. If you have 2 Allen bolts securing the flange to the transaxle, then u need to do the update. If you have hex-head bolts recessed into a spacer, then the update has been performed.
Frankly, I wouldn't have a big problem to re-use the same outer 6 bolts (Torx) to re-assemble. As I mentioned in an earlier post, Ford's first attempt at a fix with an updated and hardened spacer did not include the outer bolts - and you presumable were to use the originals. The only proper way to use a TTY fastener is to use a torque to angle process, yet this is not a procedure that is described in the service manual, hence it is really suspect in the first place if the bolt has been put under tension as intended. But, I digress. I wouldn't hesitate to re-use the bolts on my personal car but probably wouldn't on a customer's car if that makes any sense.
