First drive after brake upgrade, then - BANG!

I'm beginning to wonder if the guy that sold me the car didn't sabotage it first. Drive shaft u-joints were missing bolts, and others were loose AF!:BangHead:
For Pete's sake, did you have it inspected, by any knowledgeable person, you obviously have no idea, yet YOU are NOW finding this ****.
Be responsible for your own actions or in-actions, admit you failed Due Diligence, and stop pointing fingers at others !

EDITED for A.J.
Can't believe I just did a "Del" . .lol
