Like Tim said, lots and lots of pics. If you don't have a digital camera this would be a good time to get one. If this is your first frame off, then take more pics and get more bags to put the hardware in. Take pics in stages. Lots of pics befroe you start removing anything, pics of wiring, connections, motor mounts, body mounts, etc. I usually remove the front sheet metal first, seems like a good place to start. With the front skin removed, get lots more pics of how the suspension goes together, etc.

I trust my digital camera and computer's memory far more than I trust my own memory!!! Especially if it is going to be a considerable amount of time before I put the car back together.

Have fun, take pics as you go, and take your time. Keep us posted on how the project is going.

As you come up with more questions, don't hesitate to ask.
