Adj.brake pushrod issue

Maybe someone can help me out. I changed over from power brakes to manual on my 71 Demon. Went to newer master cyl. and got the bracket and adj. rod from mancini's. I had to modify the rod due to it being to long. I go to put it in and the original bolt holding the rod to pedal is too big to slide through the banjo hole on the rod. The eyelet on the adj. rod is only 1/2" where as the orig is 9/16. I was under the impression that it was to be plug and play and now at a loss.
