4 speed tunnel position question

I just layed the tunnel in there to see if this is about the right position for this think. I didn't get to work on it this weekend. we are priming the engine bay and other pieces but I just wanted to get some feedback here. the tunnel is real close to the floor all the way around the bottom. I have just about 25" from the center of the hole in the tunnel to the firewall. The only problem I can see is that the rear of the tunnel is going to be close to the seat. gonna have to sit the seat in here to be sure. what do you guys think. does this look about right. like I said, I didn't have a lot of time to mess with this but here s what I have so far.
