Jim,
I am with Mike B, get your truck out. If your truck is the last thing he is going to finish before he shuts down; what kind of workmanship is he going to put out. I was in a similar situation less then a year ago. The shop wasn't going out of business the business wasn't good for me. I pulled my truck out and looked for a better shop in which I found. They corrected what needed to be fixed.
Square up with the guy, get what's yours out, and do not prolong the pain.
