Its an old powerfab but all diggers are the same as far as I can see ..two pins on bucket but ones fixed the other isnt ..Just wanted to know if it was a critical measurement bettween the pins.The way Im thinking is it could either extend the bucket from opening and closing or restrict it ..awkward to explain really ..The buckets Im looking at the pins centre to centre are 95mm the one on my bucket mearsure 140mm
