Re: Amc 20(detroit locker) and Dana 30(EZ locker) ???
I think your setup will be fine, but you have to appreciate the limitations. Lockers front and rear will be excellant off road, but make driving in 4wd on snow covered streets more challenging owing to the front locker especially. Also, the Dana 30 front end is not particularly heavy duty and will need to be baby'd unless you like limping home. NO more bonzai attempts to make the obstacles. If you can't crawl up it, don't take a mad wheel spinning launch up it (as I have been known to do). I don't have a front locker, and haven't added one to my jeep for this reason. I know that if you drive hard with a front locker you will take out axles and u joints. The dana 30 uses the small u joints unless you upgrade the axles as well. You have to adapt your driving style to compensate or suffer the consequences of breakage. With an open front diff, I have enjoyed a lot of off roading and no breakage (of the front end). I would consider a selectable front locker as it would allow me to drive on the street in 4wd as I often do. And I wouldn't put that kind of money into a dana 30. The amc20 rearend will be fine as long as you don't go overboard on tire size or horsepower, and understand that even with one piece axles it still will break (twisting axle tubes is the most common).
