The metal brackets that looked like they were once fastened into the cardboard of the panel have been ripped off... So i need to put them back on, but i'm not sure how. What is the best solution for this? I tried using Quick-u-bond but it didn't work. Does anyone have any better ideas? its the steel part that has the plastic clips for attaching the panel itself onto the door.

 

Mine pulled apart some one time when I took off my door panel, I used some gorilla glue and clamped it down over night, worked fine for me!!!

 

bucket is right, there isn't an easy way once they are ripped off. I would try gluing it down overnight also...
