Today I went to change the right headlight assembly (broken top outer mounting tab, annoying bouncing beam). First I discovered my SO had given the keys to my handyman who is also my ex's son since he'd done some work while I was out of town. Couldn't find the spare keys anywhere. Got hold of him and learned that he'd borrowed his mother's car and left my truck keys in the console - and SHE was doing errands in town. Finally she showed up with the keys. Moved the truck and took out the headlamp (which requires reaching two hidden nuts to remove the turn signal and bezel). Finally gave up and removed the right battery. That improves access a lot. Got it all apart and then noticed that those weirdly-shaped retaining clips were all missing. I know I was in there a couple years ago when I changed the cracked grille support. Maybe I didn't seat them properly or didn't have them since the nylon bushings were a tight fit in the support... Anyhow they are readily available at both O'Reilly and Autozone, but I don't feel like running to town this evening (15-20 min each way). Guess I'll wait for the storm front to pass by during the night, and get them tomorrow!
