Looking for a few parts!!!

I am looking for a few parts for my 95 avenger es first i need the clear plastic piece where the back up lights are mine is broke and the junk yards around my area no luck finding it. Also anyone know where i can get the center caps for my factory rims mine are missing, also top right motor mount ( thats if your sitting in the car ) is bad called parts stores I was told it is a dealer item only so went to the just yard no luck dealer wantes $65.00 just for the rubber insert or $166.00 for the whole mount.
Can anyone help me out with any of these parts???
Thanks alot

i have a 95 avenger that i rolled about a year ago. i have another avenger for parts that got hit in the front, both are 2.0L. any parts you need i can probably come up with, but im pretty sure the motor mounts arent the same
