Hello,

I am attempting to install a garage door opener in a new garage. The
instruction manual states that the header bracket must be installed
with 2" clearance from the max height of the garage door.

When i measure the header for the 2" distance it ends up being exactly
even with the top edge of the garage door header. This is the point
where the drywall starts.

I have pictures from when the garage was being built that show there is
a 2x4 running right on top of the header and then a stud directly above
in the center of the door opening.

I was wondering if i need to cut the drywall away to mount directly to
the supports or if i can screw through the dry wall into the supports.
Also, if i should cut a longer section of drywall out, and run a 2x4
across a couple studs at the top of the header.

Thanks for any help!

Pat
