Don’t believe the 5 hr assembly time. As most of the part numbers on the part were so faded or lightly stamped that you had to measure them to figure what part they were. Don’t believe that box 1 is where you start, because you’ll be going from box to box to fine what you need. Take an extra hr, lay everything out by letter/number and all the bogs of hardware, (almost 20) by type and size, sounds like a lot of work but you’ll be glad you did when you start this long process.
