I bought my LJR 2nd hand. I am reading how a OPDA can damage other things when it fails. I was wondering if there is a way to tell if mine has been changed to the updated Crown. I looked at both and they look the same. If I can't find a definite answer how to tell the difference I will just order one. $110. No biggie but I have so many small things that cost $100+. It adds up
