It's the '68-70 kit, I believe. At least part of it is. The idler is too far out upon further inspection so I believe it is for the early setup which has no brackets behind the standoff. That would account for the alignment issue. That doesn't explain the alternator bracket problem. I have a little more than 3-13/16 from the head to the fixed bracket. This bracket was bent when I pulled it out of the pile, but it was clearly not a factory bend.
