73' B3 340 Duster pro touring build

Okay after a couple Rum & Diet Cherry Coke's (great combo) yesterday I was looking at my progress so far and thinking about future endeavor's, I am going to attempt to hide the wiper motor by flattening the current firewall motor "notch" and adding a new "mini" dodge motor to the inside of the firewall, I don't thing it will be all that tough to do but since there's all these "thinking outside the box" members watching the build, I figure I would ask if anyone has done or seen this before......I know there will be some fabrication of brackets and some re-wiring but any other help or ideas would be greatly appreciated....
