There have been a number of two wheel drive Dakota swaps done, Width with them is good.
Steve at
www.industrialchassis.com has done at least one two wheel drive Dakota swap.
Wheelbases run :
Dimensions
111.9 in (2,842 mm) (reg. short)
123.9 in (3,147 mm) (reg. long)
131.0 in (3,327 mm) (ext. cab)
That would mean you would have to do some work to get 116 for a short bed or 125-1/4 for a long bed.
Rich at Purple Monkey Kustoms in Florida has done a ton of 88/ ?? chassis swaps under AD trucks. They look good in the photos.
