the 69 12 bolt (complete) is an easy couple hour swap for the old 10 bolt

As mentioned, the 10-bolt uses smaller gears, and there were a few differen sizes for the ring gear: 7.5", 8.2", and the 8.5". The 8.5" gear is the preferred way to go if a 12-bolt can't be located, and for most purposes, is strong enough. The 12-bolt is something like 70 lbs. heavier than the 10, is rare, and is usually way more expensive.
