need a little help with torque thrust ii backspacing

[~Whitey~]

I'm ready to order wheels and am just a little unsure about the backspacing and offset.

From what I've gathered negative offset makes the dish size bigger as does less backspacing, less backspacing is also going to make the wheels stick out further, where more backspacing will bring the wheels in so you can tuck them inside the fender wells. I understand too much backspacing will make them rub.

My truck, a 69 c10 (currently down for restoration) has stock 72 spindles up front and and a stock 373 posi rear end from a 71 c10 truck. The truck has been leveled (1" front and 3" rear) I am wanting to go 17x8 all the way around. Eventually I do want to go with a 4/6 drop but that will be later.

These are the wheels I have selected; does the backspacing look correct for my application and do you think it will still be okay when I do go to a 4/6 drop?

17x8 Polished Torque Thrust II
Manufacturer Part Number VN5157873

Thanks fellas!
