Perry, backspace is easy if track width is original dimensions, (which CA is), just deduct 3 1/2 from your wheel size, no matter what size wheel you run. So if you run a 8 1/2" wheel, (whay you should be looking at) it is a 5" backspace, 9" wheel, 5 1/2" back space.
Now what is a problem is thinking your going to put 295s up there, unless the car is only planed to go straight! I installed the very first CA frame sold and have used a few since and you are going to be lucky to get 255s on it.
FWIW, We run a car with 295s up front, and the frame has been custom narrowed 3" to accomodate that and it rubs a teenie on full lock to lock steering.
