Sorry if I sounded nasty, seems like a long week already. Narrow track Dana,s will work. Wagoneers up to andincluding 79 are narrow track. I am getting ready to swap in a 79 dana 44 on the front. Will have power disc brakes and better power steering than I now have. I used **** f150 hubs and rotors so I could keep the 5 on 51/2 spacinf of my rear drums. Check the international full size jeep site, it really helped. Let me know if you need any help with what you need for the swap.
