I tend to agree with you, Bottom roller wear usually results in the links contacting the rock guards. The idler in post #13 looks pretty poor to me, but the photo isn't really taken from close enough to be 100% sure. That's why I asked for more photos showing the rest of the undercarriage components.
Could be the equalizer and swing frame bushings are shot too, making the frames splay out when its pushing. That will make the pin bosses ride the rock guards.
