She's a ton of fun (dually build on air)

Thanks bro! Obviously you figured out I meant to say axle flange to axle flange, meaning rear end of course.

Would you say that, ideally, the dimension between the inside sidewalls of the dual tires should be very near what the dimension was of the inside sidewalls of the single rear wheel tires of the C20? (hope that makes sense)

Or, expressed another way, whatever the difference in backspacing of the dually wheel and the SRW wheel, times two (for left + right)---That's how much wider I need my dually axle to be than the SRW axle.

I'm rear end shopping again, and I don't want it any wider than it absolutely has to be---but I don't want it to scuff the inner fender either. I'm going to look at a 78-ish dually rear this week. It should be fine, but hey, if you can't be anal about a rear end, what can you be anal about?
