I may be misunderstanding your question: If you put in that 14 bolt with 4:10s and leave the front diff with 3:73s the 4WD won't work correctly, you need to have the front and rear diff the same gear ratio. I did hear you can have one hundredth off, for example 4:10 & 4:11 will work. If you are asking whether the gears will swap from one another, I think they can swap, if the previous owner swapped the gears out, it most likely had 3:73s, which is what most 14 bolts w/ 6 lugs came with.
