no 6 bolt lock out hubs instead of the 5 bolt, not wheel studs. As far as all the jeeps I've owned, all narrow trac front axles had 5 bolt hub assemballys, I have not owned many wide tracs CJ axles, but as far as I can recall, all were 6 bolt hubs.
As for the sticker, don't recall seeing a sticker, my 2a has a plate on the dash, but I was not even thinking 2a's, I simply don't recall a sticker on a 73 and newer CJ dash.
I do recall there being a vin plate just under the booster on the fire wall that was attached to the out side of the pedal assemablly and I could have sworn that they also had the vin plate rivited directly to the windshield (not the motor cover like a YJ)
I could be mistaken, I'm gonna check CJ windshields I have at home and dashes; I have probably 10-12 CJ dashes hanging in my shed.
