anybody done one of these installs yet? I installed a Grizzly locker in my 11.5 and went to install the elocker in the front and noticed it will require alot of grinding of the case to make it fit, there were no instructions of course and cant get a hold of tech support also wondering about the locator tab on the ring that rotates on ring gear side of locker if it needs a massage also any advice would be appreciated.
