For anyone wondering about finding the measurements of a 180, I've learned that most 180s are sold by center line radius, which is from the beginning of the bend to the middle of the bend, to figure out how wide the whole unit is going to be, you double the center line radius. So most 3 inch 180s are 4.5 clr, which makes the 180 9 inches from the center of one leg to the center of the other leg.
