Had mine rebuilt by local Ford house at around 30k. Replaced a few synchros, but thrid gear was giving me the most trouble. I just pulled the entire top shifting mech. out and replaced a simple bolt that the damn Ford dealer overtightened, causing it to break. The shifter had around 4-5 inches of play from 1-2, 3-4, etc. Forward and back. They would have said tough ****, so I got brave and pulled apart to look at it. The Ford service is second-rate at best (but you probably already know that.) Hope this helps. If you need more specific info. PM me and I'll see about getting you a copy of the service invoice.
