Indeed my memory failed me. See below,

This is a picture I took when I did a 94 9k cde auto to 5 speed conversion last November. The tensioner top bolt is bolted onto the timing cover. The bottom of the tensioner is attached to the bracket. The bracket has a round pin where the tensioner bottom connection is fastened by a circlip so it can rotate.
Now the bracket itself. You will note the bracket is triangular. It is mounted onto the timing cover by three torx screws. One of the three is countersunk. If memory serves (which it apparently didn't the previous time) the three torx screws are to be tightened to 15 ft-lbs. If only the bracket failed, I consider you lucky. It is much less expensive than if the top tensioner bolt took out the mounting attachment on the timing cover, in which case you'll have to replace the timing cover.
BTW I don't think it is difficult to remove the broken bolt shank stuck in the hole. Experience tells me the shank is loose in the hole. You know the bolt tension is no longer there. So there is nothing much to prevent the shank from being extracted. A pair of needle nose pliers and patience will do.
