Including the six bolt Dakota can be changed tp five bolt by replacing the brake rotors

Quote
5 lug Dakota were 1988 through 1990.
6 lug Dakotas started in 1991 and were present through the end of the truck line.
The 1991 through 1996 Dakota 6 lug stuff could be swapped by simply buying the 5 lug rotors on the front, and replacing the axle shafts (same size axle, the different sizes do not interchange) & drums on the rear.
