4 speed tunnel position question

I don't remember it being to difficult to figure like sireland said. I did have the trans in the car without the shifter. I cut a hole in the auto pan and then installed the shifter and used the stick and hole as a centering guide. Marked the outside parameter of the new 4-spd tunnel and cut it out leaving a half inch to an inch inside the marked area. I set the drivers bucket in and made sure I had proper clearance to adjust seat, which I did, then welded it in.
