I don't have it handy right now, but if you look at Sect 12, Sheet 8.00 in the FAM, it shows the "guide". It's a z-shaped piece of sheet metal with a bolt hole thru it. I'm also seeing that same figure shows the battery to starter hot wire routed thru a clip on the other end of that ground strap. I remember taking that off of my truck. Which answers the question about that flush screw on the bell housing not being used for a battery cable clamp. Found the photo of when I removed it.
