Hi all

Hi all my name is nick and I have bought a 1975 dodge dart swinger 2 door with 6 cylinder engine. I came hoping to find answers to questions I have, and hope someone can point me in the right direction. Like is there an adapter for new windshield wiper blades? Or where can I get ones that fit my car as Autozone and like stores have no attachments that fit my dart. Also what size tires fit the stock rims? Thank you for your time guys and will post a picture when I can.
