Sliding door panel will not stay on


New member
The inside vinyl door panel on my 86 Westfalia started lifting off and jamming on the back doorway pillar when I opened it and pulled back to slide it. I removed it and found some of the trim screws had broken and the mdf backing itself had cracked a bit.
I glued in some new trim screws, but they don't seem to hold very well. Additionally, the panel has developed an outwards bow so that when I try to slide the door back it again catches on the pillar. Does anybody know where I could get good trim screws, or a better way to fasten this panel back on? It would seem also that my sliding door is a bit out of adjustment so that this panel edge may be too close to the body when it goes out and back as the door opens...
