So I ordered most of the steel I will need to make the chassis. There is something I need to figure out first and could use some help.
I will be making essentially a book chassis except for every transverse tube that is in the middle is sort-of moved back 4 inches (and IRS), similar to what a user did in another forum (forum is down at the moment will post when/ if I can, user is skinnyG on grassrootsmotorsports EDIT:

Anyway, here are some pictures to explain what I mean. Note: Green represents my chassis and red represents the book chassis.

As you probably guess, the transverse tubes moving back (along with everything that lines up with them, such as the scuttle/ dash) will shrink the cockpit opening and lengthen the nose a little bit. I think that the book chassis has just a little bit too stubby of a nose and too long of a cockpit for me. I also want to be able to reach the dashboard while strapped in, as I will be putting switches on there.
I plan to order the "lotus s2 +1.5in height" nose from Curtis unlimited. I would order the TTL nose from kinetic, but I want to have a slight horizontal bump around the suspension points and the pictures I have seen of the curtis nose have this. My problem is that I cannot find any dimensions for this nose. My thinking is that if I make the top main chassis tubes the same outer width as the rear most part of the nose then the lines will flow smoothly and for now I have used the dimensions (very rough dimensions) of the TTL nose. Does any one have or would be willing to make some more accurate dimensions of either of these noses? I will return the favor with as accurate of a 3D model as I can make.
