Dakota Wheel Backspacing Question

[ProJunkRacing]

I have a 94 Dakota WIth stock rims on it , i currently run 31/10.5/r15 dunlop mud rovers ,and i am soon to order 33/14/15 Boggers. What i need to know is what backspacing u all would suggest to get it wide ,but to not have any rubbing. It will have a 3" bl and finish cranking the torsion bars too besides.

Thanks Phil
