The tendency toward 3rd gear grind is a natural feature of this transmission. Installing the currently available synchro parts from Ford you may never be happy or not happy for long. If you can find the three part blocker rings you will be happier. As far as I know, Terry is the only one that has these. When he heard they were being discontinued, he bought up all of Ford's inventory.
That said, before you spend the money and effort on a trans overhaul, try a fluid change. My tendency toward 3rd gear grind completely went away, over time, after installing Ford Honey fluid. I also used 2 oz of Ford Friction Modifier since at the time I made the change it was preferred. Since then many have reported that the Friction Modifier is not needed.
