My guess would be a 1/2 ton front axle. 6 lugs ended in 70 for older trucks. The
12 bolt, 8 lug rear, Dana 60, was used in 3/4 ton late 60s to 70s.
Another source of info, especially for the later model trucks is

When I checked I found that Dana 60 has 10 bolt. Where did I go wrong?
Raider....are you saying that the brakes are locked? This is a common issue with trucks sitting a long time. Unscrew the bleeder. Then it's bang bang, lever, twist, pry and bang and heat and soak and bang and maybe a puller. Sometimes things get broken but parts are available.
Also one thing for sure, you should not continue in the welcome section. Our forums have descriptions for what they are for. See General, driveline, Tons O Fun...........
