What motor mount brackets do I need?

I agree, something is not right, but here is where I get confused.

  • LA blocks (pre-magnum) passenger side had 4 bolt holes where there are now 3, right?
  • This has the right bolt pattern for a drivers side, but wrong width, and was sold to me as a take-off set.
  • My '68's mount on that side is identical, but has 4 holes. (this set also had heat shields, whatever it came off)
  • The pic below is on eBay as a set of 70/71 318 mounts, and IDENTICAL to what I have right now, both sides.

both of these are for the same side of the engine drivers side
