i am trying to get the front input shaft to the transfer case off. i have removed my skid plate (thanks keith) and i am trying to get the 4 bolts on the flange off. i need a 5/8" with a 6pt box end so that i don't round off my bolts, but all of my box ends are 12pt. does sears sell such a wrench? all i have or seen have been 12pt. thanks. scott.
