Can anyone who has seen the new M25 / M45s, tell me whether the heads have mounting holes at the front in addition to the back?

As you can see here, the mounts are holding the M20s from the back (photo shamefully stolen from hookem202's thread ):

I want to know whether the mounts can hold the heads from the front, as my bumper cover goes back only 1 inch, even though there is plenty of space behind it. Otherwise the only way would be a custom mount.
