I'm in the same boat as 240zboy, except I've been working on mine for 3 years. I also did what you did, immediately started tearing into things (I was 14 and curious) I've lost nuts and bolts, and rear brake parts, and other little things. I had to literally pay for my mistakes, and I didn't like it. If your Z runs, get it to where it's safe and reliable. I wish I would have followed my own advice! It takes time, and like 240zboy said, trick is to bum rides
