Not to happy with my wheels

[Rod Run]

I finally received my wheels and tires from Discount Tire Direct earlier this week. I ordered staggered 17" soft 8's and I told them that I wanted them because they had the 4 1/2 & 5" backspacing.

They told me they didn't have the Cragars, but they had Vision and they were the same thing, so I bought them.

Now that I'm a looking around online, it seems their backspacing is 4" & 4 1/2". I'm pretty pissed right now and can't call until tomorrow. I am far from mounting the body on the chassis, so I can't go taking chances, when a lot of people on here have proven out that the Cragar offsets already work. It's going to be a LONG sleepless night for me.

I can only imagine how much of a pain in the ass this is going to be, to get straightened out.
