I hope some of you guys who have modified the 5x8 Red Trailer can answer a quick question. When it comes to cutting and installing the 2x4 cross rail in place of the 2 metal ones that go into the side rails, how tall should the 2x4 be cut to? I have the 2x4 in but it's taller than the metal cross rails. What size do I need to cut it down to to make it fit flush with the red metal cross members? Yeah, I am thinking too much but I HAVE started my floor finally.
