those are from a super duty like you said from an 04 and down, you will have more limited options with these axles compared to some from the non super duty versions, these have the crappy hubs, vacuum, different bolt pattern

for that price you can find a set with a king pin 60 and a 10.25 for the same price or cheaper, you can usually find a 60 around the 8-900 range and a rear for ~150 or less
