Well, if anyone finds this thread by searching, it looks like the only way to get to that bolt is to remove the drivers side accessory bracket from the head. Once that was completely loose, I could reach the bolt. The motorcraft harness is nice in that it has all the clips and holddowns being a direct replacement. Total time it took me was about 5 hours. Called a shop and they said book was 3 hours, their rate at $88/hr means I can spend ~$300 guilt free on the racecar
BTW, it's 68* here, so I couldn't use that excuse.
