Gov-Lok info. Didn\'t know this. I got my Off-Road Adventures(4wpw mag) mag last night. There is a GM axle info article in it and it has a little side article about Gov-loks. Bear with me I forgot the mag at home. They say Eaton never called it a "Gov-Lok" and it is just a name that has caught on over the years for its governer locking mechanism. BUt they do state that the pre '75 "Gov-Loks" were more of a genuine locker! And they state the post '75 units are more a limited slip. Anyone have one of both style(pre '75 and post '75) that have noticed a difference or can tell by looking? I know that the Gov-Loks are not saught-after and most could care less, but I just thought this was kind of a cool thing.
