Problem is fixed. I wrestled with the idea of fixing it myself or letting a local Ford dealer fix it. I decided to let the dealer do it for two reasons ---
1) I had never done this exact repair before.
2) If something DOES go wrong with the repair, I'll be hitting them up to make it right.
I've been running this thing prettty hard since the repair has been done. Many, many pulls in gears 1 and 2 to 6300-6400 rpm. And quite a few in gears 3 and 4 to 6100-6200 rpm. [My engine rev limiter is set at 6400 rpm.]
I'm happy that the problem is fixed ---- and I truly appreciate the input that I got from people on this forum.
