Ball joints & CA Bushings?

Its for my 71 dart with manual drum brakes, i allready have inner/outer tie rods i just bought, are there any places that carry these parts for reasonable prices, i can order the upper BJs from O"Reilly or AZ for 30.00 each, should i run nylon upper bushings or stay with stock.

One more thing, what size socket is needed for the A body upper joints, who carries it?
