Trying to figure out what gears came stock in my 1985 K5 4WD. I know that my grandfather never had them replaced so whatever the good General put in there at the factory is what's still in there right now. /forums/images/graemlins/wink.gif Is there a # I can look for somewhere on the differential or maybe a way to decode the VIN? Apologies if this has been asked a million times before. I did a quick cursory search of this forum and couldn't find any exact hits on it.
