I took my Dads car to the chop shop for drug money
He hasn't noticed his car is missing?
Not yet but soon he will.
Unfortunately, that decision is made and can't be taken back. Now, your best move is to come clean to your father about what you did. Hopefully he understands that you made a poor decision, which everyone does from time to time, and forgives you for it.
Are you stupid? He will kill me when he finds out. I need to get rid of him.
You should try to get a job to replace the stolen parts as soon as you can. You need to tell him about it and your addiction so you can get help and he can drive safely.
