Now I've done it....
 

was going to put the cowl back on with my new screen and the little clip that you slide down to get the wiper arm of went SNAP! why does this always happen to me? Anyway, how do I get the wiper arm off now? Any help is greatly appreciated.

replace
 

Cut the end in half with a cutoff wheel and replace the arm. I have an extra if you need it....

i used a pry bar and it worked just fine, just be careful.
