Will the six lug steering knuckles with spindles hubs and rotors from a 1991 Dakota longbed 2WD reto-fit onto an 87 dakota 2WD longbed front end?

I picked up a cheap 91 that has new brakes bearings and hubs all around but the cab is junk. Now I find my 87 driver needs a complete brake system overhaul.

I am going to swap out the rear axle, transmission, and fuel injection anyway so thought why not do the front as much as possible along with it.

 

I believe the rotor/hub will swap over. I think I remember a few guys swapping it over to convert the bolt pattern to the 5 lug which has tons more options on aftermarket rims.
