Its the Gov-Lock alright. I had one on my old '81 SWB K10. While it didn't blow up on me, the pinion nut fell off and the pinion then fell back and jammed itself between the housing and the ring gear causing a lock up. /forums/images/graemlins/histerical.gif
But regardless, thats definitely a Gov-Lock. /forums/images/graemlins/waytogo.gif
