hey guys, i have a Bradco 617 trencher for my bobcat. i want to upgrade the crumber to the one used on the Bradco 625 trencher. i need some measurements from the 625 crumber bar to get this in the correct position. if you own one of the 625 models, i need the measurement from the end of crumber bar to the 2 holes used to mount the plates that allow the crumber to move back and forth. i'm over 100 miles from the nearest location where i can see a new 625 up close to get these measurements. i'm hoping someone here has a Bradco 625 and can help me out with the measurements. thanks for reading and any help will be greatly appreciated. bubba24
