wiper arms

I wanted to see if i can get just a flat style wiper blade (bosh) others, it dont have the arm because the arm is built into the blade itself, smooth and small look, on fox body's they have the arm and at the end of the arm they have a rod at the end of them, most cars now have that hook at the end of them. most new good/better wiper blades use that hook, there is no hole in it to put on a fox body wiper arm. I wanted to use somthing like that for cosmeticly and better performance. I also thought they where 13 in. blades on a fox, oh i could be wrong, i wouldt put a big blade cuz it would just anoy me if it was hitting my trim hahaha.
