Thank you! Fortunately there were a few trim pieces floating around eBay. I also picked up a radio from OEM Radios to fix the tape deck- installed it yesterday, very easy to do and works like a champ.
The only thing I'm going to semi-focus on now is the rear glass latch release (possibly a solenoid issue?). I can open it from the outside with a key just fine. When I push on the tailgate release button without the key, I hear a click (like a solenoid) but the latch won't open. Likewise, the button under the dash doesn't unlatch the rear hatch (although I can't hear if there s a clicking sound coming from the solenoid or not, I'll have to have my wife stand next to the tailgate to see if she hears anything).
Any suggestions?
