Rat Rod Rockers! Screenplay

Down to the very last scene of the Rat Rod Rockers! movie screenplay. I have already written the end sequence. This particular scene is about three scenes from the end. A crucial turning point in character action. i am having a dilemma with how the lead character fights the villain. I have already written the outcome but need to make the lead up convincing. I will get it, but maybe not tonight as I hoped. I am running out of time. We start shooting in a few weeks.
