A replacement floor assembly may include a base member having a top side, a bottom side, a front end, a rear end, a left side, and a right side. The front end and forward portions of the left and right sides define a forward section of the base member, whereas the rear end and rear portions of the left and right sides define a rear section of the base member. A first outboard flange member is mounted to at least a portion of the left side of the base member and a second outboard flange member is mounted to at least a portion of the right side of said base member. A front flange member is mounted to at least a portion of the front end of said base member so that at least portions of the forward section of the base member, the first and second outboard flange members, and the front flange member define a battery well.
