back spacing and sizes

I am looking to run something like this setup 215/65 front and 255/60 rear , Will the rear size fit ? Would 3 3/4 or 4.5 back spacing work ? 72 Duster with a large 11" rotors front , 8 3/4 rear installed ,,looking at Torq thrust polished or the Torq thrust D Black or maybe good ole Cragar's but open to any suggestions on which wheel some like better than others ?
