i have a dana 70 in my 93 4x4 w250 srw with 3.54's that I'm converting to a w350 dually. i recently got a dana 70-2u with 7.17's in it. i would like to know if i can use the 3.54s out of my dana 70 srw and put them in my 2u. i know for sure that my 2u has 35 spline and my 70 has 32 i think. so can i use my 70 side gears and use them with my 3.54s? will it bolt up or will i have to buy a very expensive 3.54 kit for my 70-2u?

thanks hope this isn't too confusing haha

will

unfortunatly those numbers do not come up. on the axle tube there should be a hand stamped number that is 6 or 7 digits long that starts with a 6. that is the dana BOM # that I would need off both housings.
