I bought a sliding barn door that was the right width but a bit too tall. The
bottom has a groove for a guide, so in order to shorten the door, I cut a
couple inches off the top.
The trouble is, I cut off the hardwood at the top of the door that the roller
assembly screws into and now all that's left is the particle board interior.
The particle board isn't strong enough to hold the weight of the door on the
rollers. So... I need to figure out how to attach the rollers to the top of
the door, with only particle board to screw into. (In retrospect, I clearly
should have cut extra height off the bottom - too late now.) I'm wondering if
I drill holes, fill them with epoxy, and then set the screws in place if that
will be strong enough. Thoughts?

Here is the door for reference:
