Everyone has a system, that works with their way of doing things. For me, Once the main tub is painted, I like to install firewall stuff (both inside and out) as well as glass, and as much engine stuff as possible, before the doors and front clip go on. Less parts to lean and crawl over = less scratches, chips etc. to have to go back and fix later. Plus the firewall, engine etc. is so much easier to get at. As they say, "work smarter, not harder".
A few "before" shots of the a/c box. I always take lots of multi angle shots, before I take something apart. It makes assembly a lot easier, as the the old memory, is quite as good as an elephants!
