I'm going to go in tomorrow or Monday and tell him I need it by April 4th. He's had the parts since December and my car since September. Is this okay to do? What should I keep in mind before doing this? Should I be prepared fir backlash? If it's not done by April 4th my dad and I and some friends will go and get it and my parts. I'm so worried about this. He could give me the wrong parts or anything could happen. Got a million things running through my head about this.
