Maybe,,maybe not. That's just how we built them back then. It was just pure fun and creativity. We built them the way we wanted to, the way they looked good to us, and if that required using all the parts in the box...so be it. Sometimes all the decals on the sheet as well. A lot of us had to mow a few lawns, do a few odd jobs or collect a cart full of soda bottles to be able to go the five and dime and buy one of these kits. If you were lucky a can and a few square bottles of Testor's PLA. Yes it was a blast, and there were no internet critics.
