When I get back from vacation I'm going to look at a FF14 bolt out of a mid 80s van. I know I'll have to relocate the perches and shock mounts but I have a question about IDing a gov-loc. I know they have 3 cross pins but does an open dif have 3 also? Does it look simular to a 12 bolt gov-loc, big chunk, lil springs and stuff? Never been into a FF before, will the same hub socket you use on the front work on this axle? Do you need a hub socket to get into the brakes? I'm so ignorant. /forums/images/icons/confused.gif If this thing turns out to be a gov-loc is Chevy the only place I can get an open carrier to run a detroit? Any body know the cost on that?
