Got it fixed. I built a wooden block that fit the inside of the track. Put a wood screw through either side and it's done. Well it took a little longer than that. Take the door off, mark the pocket side of the track for the door stop reference, remove the track (not an easy job). Put it all together in my shop, make sure the door opened and the block stopped correctly. Now the harder part, putting it back together. Once done it all worked well. RV Will by long gone before this pocket door gets out of control again.
Thanks for all the input
