So basically we need the horizontal PVC piece over the door perfectly straight, right?

Is that groove in the PVC large enough that you could slide the small edge of an "L" shaped extruded aluminum support into it?

Here is another idea...better, I think...

Pull out those little 1/4" pins across the top. Open the door and jack up the piece of PVC so it's level. Align a flat piece of aluminum...right now I'm thinking 1/8" flat extruded aluminum stock...along the PVC on the inside, and mark the positions of the holes for the pins that were removed. Drill these out at maybe 1/4-5/16". Then attach the aluminum flat against the PVC throught pin holes with something...let's see...thinking...metal screws might work but risk cracking the PVC...I think the first thing I would try would be plastic wall anchors, those barbed anchors you drive into the drywall to hang stuff with...find the larger ones and insert the anchor through the aluminum into the PVC. If it weren't tight enough, you could just drive the screw into the wall anchor and it would grab the PVC better.

Something like this diagram. This way, if it didn't work, you haven't damaged or altered the basic frame in any way.
