not an A body, but an 8-1/4 question none the less...

Will the axles from an gen I Dakota swap out with the axles from a gen III Dakota? Both rears are 8-1/4. Need to keep the 6 bolt axles and the rear I have a lead on is an earlier 5 bolt axle rear... Can I simply swap the axles/drums and be good to go? it is a 3.55 limited slip/sure grip with only 120k on it. I can get it for $80 or less.
