I am installing a industrial chassis dakota front end in my truck and was wondering since all the tech articles say the tread width is perfect would a dakota rear end also be a good fit?

 

I measured a Dakota frame at the wreckers some time ago.I was thinking of using the Dakota frame for a chassis swap on my 56.The wheelbase was perfect at 111.9, but the frame rails had quite a dip in them under the cab and the rear end was to wide. If memory serves me I think the Dakota rear end is about 2 in wider than your stock rear end.
