HELP!! I've gotten the door panel piece re-upholstered and the new black fabric is glued down.. However, since I broke off those melted plastic pieces that holds the armrest to the door panel, how do I get them to stay? I'm afraid of using screws as I might drill through the other side..

Solutions?

My setup will look like this pic:

 

There are a number of plastic glues to use, just go to the hardware store and buy!!
