what is the back spacing?

[killer camro]

i have a 70 camaro and need help figuring out good size to use. i wanted to use bad billet wheels in a 18'' rim but dont know what back spacing would be and the off set that would give me a deep look. i only get one shot when i go to order the wheels. cause the wheels are made to my spec's. so if anyone can help me please do so. i'm going to drop the car with 2'' hotchkis leafs and springs for the front. thanks vinny
