gradall buckets, G660 size attachments fir G3 size machine?

[markct]

i have a gradall G3XR excavator, its a 35,000 lbs machine and i have been looking for a narrow trenching bucket for it, i see alot of stuff for the larger G660 size machines but dont know if the quick tach setup is the same, anyone familuar with gradalls? i havent found one around that i could measure

The only buckets that I can see form there parts pages are ones that fit the G3 series machines (ie) G3W- G3WD - G3R the mounting is different for the 660 and up machines

thanks, i suspected they were different but wasnt sure, i know the 660 size machines are alot heavier and larger than the g3
