Problem is that there really is not any space to even put your hands in let alone mark you spot.

But my basic question: which is preferred and why?

a. Should belt and seat back mount to firewall.
b. Should belt and seat back mount to roll bar ( i prefer this but I cannot figure a way to do this given the space available.).
c. Should belt to fire wall and seat back mount to roll bar.
d. Should belt to roll bar and seat back mount to firewall.

Please note that I have an eight paint roll cage.

I would also agree to start with the rule book for the racing group or groups that you intend to run with. It will save you lots of grief when you go thru tech inspection for the first time. The rule books usually have some guidelines for belt attachment that can be helpful. Simpson safety equipment and Schroth equipment have some good guidelines on their site for belt location, attachment and angles. I have helped out in tech inspection in the past and it sometimes pays to do some research early on to save your self some issues at tech later.
