Frame-Off Restoration

Well, purchased a 69 convertible six months ago. Was not advertised as numbers matching car. After inspection, it has original block (don't know about heads yet), 4-sp transmission, and 3.70 posi rear end. After driving awhile, have concluded most everything in suspension and steering is original as well. Decided my retirement project is going to be a frame-off restoration in my home garage. Have not retired yet, but soon I hope. Any suggestions on the best way to plan for this endeavor?

The first thing that comes to my mind is to bag and label every nut, bolt, screw, etc. Take pictures and label each vacuum hose and wiring connections. Good luck.
