Backspacing of Stock Steelies (6 Lug)?

Does anyone know the backspacing of the stock steel 6 lug wheels? I'm thinking about ordering some Wheeler's black steelies but don't know to go with the A (4") or B (4.5") ones. If the stock wheels are 4" than I may get the A's and use my Spidertrax spacers. If they're 4.5" then I'll get the B's and definitely use the spacers.

Thanks.

 

What is your goal for these rims 33" tires? Desired backspacing is 4.5" stock bs for our trucks is 5.5"

 

Thanks for the prompt reply. I am running 265/75r16's (basically 32's) and plan to stick with them so I don't overweight the 4 banger. I just put an AAL on the back and cranked up the 5100's to 2.5 so I'm trying to get the wider stance than stock. I had the stock steelies with the Spidertrax and loved the look.

 

Pretty sure the weight won't bother that stout little engine.
