Registration and Posting Agreement
I've been told by many, many rear end shops the G.M. Gov-Loc is junk. I know on E-Bay and local classified ads they are mis represented as Eaton Positraction units. I had one a very short time in my 1984 C-10 with a mild built smallblock and destroyed it after a few power brake sessions. I replaced it with an Eaton Positraction, I believe part number ended with 559. I would definetely save time and money and buy the Eaton. The Eaton unit loves to make 2 long black lines on the pavement. Ken
