Only the early Dakota's (pre '97) have a 4.5" bolt pattern, the later ones run a 6 bolt pattern, and then 5 on 5.5". The early ones will be a 8.25" rear, later ones are a 9.25". But, even the early '87-'96 Daks have a 69.4" track width, which is almost 14" wider than the track on an A-body (55.6").
So, even the early ones with the correct bolt pattern are too wide for an A-body. You'd need to have the rear end narrowed, and either buy new axles or sort out shortening and re-splining the Daks.
