  #sflorg Well, damn. . .broken handle on the driver side of the truck. Was hoping it was just a clip, but after getting the panel and handle off—it was the handle. Part on order—and such is life. That's how I spent my afternoon. I'm getting to old for this mechanical work. 😁 See you in the morning. Heidi-Ann
