Careful where you put it on the girth. The edges of that plate can rub against the underside of the saddle flap and wear it thin or, if it's below the edge of the flap, wear a hole in your boots or chaps...and I got a pair of $250 in 1994 full chaps complete with "mystery" hole mid calf to prove that.
I yanked it off when I realized what was happening about '96 and never replaced it or installed another. I have intials carved on the backside near the buckles or just use a black laundry marker on the inside of the elastic instead. Works fine, doesn't show and no holes.
When opportunity knocks it's wearing overalls and looks like work.
