I'll try to get you a picture tomorrow. I think they are just about flush. Without the spacers they would have rubbed the inside of the wheel wells. 3-3.5 inch spacers may make it reasonable with the wide box. I think the tires will be a bit inboard no matter what.
Ramsey says that you don't want the track widths to be exactly the same front and rear.
I saw a pict of a wide box running singles. I think it was called rhino ambo. Did look kind of funny with the tires inboard.
I saw a dodge dually running 6 military 37 last week. Made me think of you looked to be on narrow rims. I think it would be overkill.
Pretty much given up on the dually. It can be done, just not reasonably, and I can't quite bring myself to spend the $400+ dollars/ea. for tall/skinny tires.
If plan B (stock H1 setup all around) doesn't pan out in the rear I'm stuck with recentering all the rims, which is pretty ok, it's just not the look I wanted this time around. I figured a way around the bolt pattern issue up front. Standard axle up front, and there is a place (whose name escapes me at the moment) that makes dually adapters for a front axle, which also can adapt the pattern from 8x170 to 8x6.5. They look just like the factory adapters.
Found that Rhino ambo, but without knowing what he's got going on as far as rear axle (SA, Dually axle, spacers, etc) it's hard to make a judgement. I'm guessing it's a sterling back there with spacers, but those are a few inches narrower stock than the ambo dually axle. My guess is that is what I would like in the rear if I used my dually axle, spacers, and the stock H1 rims. But dang if it aint hard to tell just what it really looks like from a picture.
