I make a list of the things I can think that needs to be done, I use MS word to make a list.
After I make the list I categorical things, engine, trans, brakes, body etc.. what needs done. then you can further categorize buy big job, small job, money or time.
Many things just take time if your reconditioning parts, some of which you can do in the house. needing a steering wheel shouldn't hold up a column the wheel can be added anytime.
go get some boxes, I use totes, but oil boxes work good also they are generally all the same size and strong - and label them - engine assys pulleys covers etc. door, handle door parts. Interior etc. organised your garage on your in between time. It makes everything a lot easier to find when you approach that part of the project. find old butter tubs or sealable jars for the small stuff nuts, bolts and screws, put them in the boxes with the other parts.
For me getting it mobile is always my first priority, when I can, so I can move it around I tend to keep more interest in the project if I do that.
