I measured what was left and I have just over 68" remaining after I built it. Added a short straight section to the bulk head drain when I got my ball valves, and a small section of silicon tubing will add two hose clamps to this at some point if needed will post a pic soon. So the bottom line was that I built this with @4.33' of 1/2" copper tubing plus the tees and elbows! Just remember measure twice and cut once straight and clean and you should be ok.
Brian, do you need the extra copper for your build? Let me know!
