what backspace with this combo?????

[jwillia2]

hey guys

a good friend of mine just purchased a 69 camaro that had a set of heit's tubular uppers and lowers.. on a 8 inch wheel what backspacing does he need since they are an inch narrower..... and how wide can he go on the rear with stock wheelhousings??? also if he narrows the rear a couple of inches that should give him a nicer lip on the back right??? would a 17x10 be to tight ???? i have a mini tubbed car and my 11's don't have too much extra space...


thanks justin
