I found that as I went along, there were things I needed to or wanted to revisit (tighten a bolt, make a final adjustment, etc...). I used Manila shipping tags to write myself a note on what I completed, needed to do or recheck and wired it the the component that I needed to revisit. Sticky notes do the same thing but tend to fall off.
I also keep some spiral steno pads to write myself notes as I think of things I need and whatnot. I also found that a right angle drill and a 12” (1/8”) drill bit both came in handy. The 12” bit probably much more so than a right angle drill. A couple times a screw machine length drill bit was helpful too. I’m sure once you build one or two of these cars, you know where you can get a drill into and where you can’t. THe long drill bit enabled me to drill where I couldn’t necessarily get a drill in close, but could still get a riveter in
