I wasn't sure if I needed the room or not so I just made it that big. The frame I started with was kind of butchered. Now looking back, the rear section was sort of pointing up on a slight rake so I didn't want to change that. I think it is supposed to be strait not going up. I might just cut it off and weld in new metal. The more I think about it I might just build a new set of rails I'm almost there now.
