David,
I went back to look at my truck. Regarding hole #10, you are correct. That does not correspond to where a cage nut is placed. I do not have that hole either and there is nothing I am aware that requires that hole. I recommend you fill that hole in 12 1/2 hours!
Regarding holes #8 and lower #6a you are correct again. In fact, I have a clip for the wire in lower #6. Upper #6 is present in my truck also, but nothing in it. I probably should put a clip in #8, the wire is right there (on the inside, of course).
This has helped me, thanks.
Regards,
Kent
