backspacing help on rear

I want to go with 15x10s on the rear of a 69, what is the best backspace to go with so they dont rub anywhere when the truck is dropped on the air bags. Id really appreciate any input!

Any ideas, I know lots have 10s on the back. Im just worried about clearance when they are tucked in the wheel wells. normal ride hight gives them more room.

Re: backspacing help on rear

There are too many varibles.
You need to do the drop.
Center the rearend with an adjustable track bar.
Then measure.

Do you still have the original "narrow" 6-lug '69 rearend?
Or the "wider" 71-72 (and mid '70) rearend?
