Colin, I had the same trouble with steel angle here and had the edges water / lazer cut to size. (water is better because I didn't have to straighten it) I don't know what people do in other parts of the world, Riveted carriers have approx. 7mm side armour. Here I can only buy 6mm or 8mm plate. Maybe in Australia and other larger countries you have more choice? Everything is a compromise, but the small variations you have to make will be of little consequence. Mechanically minded people, like us, will be in awe of what you have done.
