Just purchased a 1979 Komatsu d31p-16. Needing help with the blade tilt "dog bone" as i call it. Original was broken and missing and someone has previously fabricated one that is a bit to long i believe, and its putting the blade in a bind as the top of the blade is leaned to far forward.... Anyone out there have one they could get a quick measurement center to center? It would be a great help. Thanks!
