Help Clueless on Backspacing

I have a bone stock 1972 LWB 1/2 ton 402BB GMC rear leaf spring. It currently has 5 on 5 15" wheels, but I covet some torq thrust 17".(unless someone has a better suggestion.)

Can someone who knows what they are talking about explain this to me? I have seen charts and it is like chineese to me....backspacing, centerline, offset......I don't know.

I've been a Jeep guy a long time and only dealt in wheel size and tire size, never backspacing. HELP! Thanks in advance.

Re: Help Clueless on Backspacing

hey Indy Rich, I have a set of Torque Thrust II's on my truck right now and I am getting ready to sell them if you are interested. They are 17" . I can send you some pictures if you are interested.
