I got a good look at a 6.0 in a friend's shop the other day. They do have a single bolt hole in the front on each side. It's been a while since I've seen a set of V8 mounts, but if I remember correctly they only have 1 hole, the lower of the 2 factory holes on each block. I bet I could make one work pretty clean with a set of stock V8 mounts, may have to fab the top piece, but that's easy.
