Tired of mechanic shop

I took my truck to the shop to get a new engine installed. I did that because I didn’t have space or the right major tools. They also installed my Tremec TKX 5 speed. After picking the truck up, driving it home, and looking over the work, I’ve found some janky work done on my clutch rather than replace the linkage. I’ll post a video of the clutch fork while I have someone else pushing the clutch. I’ve never worked on a transmission or clutch before, but I’m wondering if this is because the throw out bearing is improperly installed. I’d my clutch linkage missing an adjustment rod where the spring is? Any suggestion would be helpful and appreciated.

I'm in a similar situation after having my clutch replaced. The adjustment was all off and the clutch pedal wouldn't return all the way. I could tap it up with my foot but it would not return on my own. Additionally, the clutch would engage almost as soon as I lifted my foot from having the clutch pushed all the way down. Never operated one like that on any truck I've driven. Shop claims it's fine but I don't buy it. First, found the adjustment rod to the fork was not set correctly. Setting that set my clutch engagement a little higher from off the floor. (It does engage really well and tells me the old one was worse than I thought) Next, I noticed the clutch fork return spring was missing completely. They did add the small retaining spring to keep the adjuster in contact with the fork. I replaced that (as shown in your pics) and now the pedal returns pretty close to all the way up, nearly in line with the brake pedal.

I see you're missing that small retaining spring. Also, in your first pic the return spring is connected to a higher spot on the frame. I used the hole below the shock mount. That keeps the spring better inline with the movement of the clutch fork IMO. The long rod is just excess material that came with the generic spring - I trimmed mine. Last, you're missing the boot on the housing that goes around the clutch fork.

The throw out bearing or release bearing (whatever you want to call it) was installed with the spring tab of the clutch fork on the outside of the flange of the bearing instead of inside. This creates a gap in between the bearing and the clutch fork.
