you need the ubolt plates that hold them to the springs for dana 60 front or 14 bolt rear like in your picture . and ubolts will be bigger also. this is for the bigger axle tube dia over the 1/2 ton stuff.
and the rear spring pad width is 42" for 1/2 and 3/4 ton 40" for 1ton. this is center of the leaf spring pad to center of other side pad.
and driveshafts will be basicly the same on front but dana 60 will need to check length as the housing is bigger and that makes the shaft just a little shorter. but if you have a lift then might be perfect.
rear will need a trick joint for 1/2 ton joint to a 3/4 or 1ton joint. i dont recall the part # off the top of my head sorry.
otherwise its fairly basic bolt in job.
