Extend-a-Fender (lots of pics)

31913 or very close to that is the Extend a Fenders

I'm checking out these flares too and I'm finding two different descriptions. Part number 31913-11 from Bushwacker says they are 1.25 inches wide but other websites are saying .75 inches for the same number. Can anyone clear this up at all?
