I think I screwed up my wheel order...

[County]

SO, I'm in Afghanistan and found some wheels I liked on sale and pulled the trigger without having the truck in front of me. I'm still a C10 newb, but did a bunch of searches and thought I had a pretty good guess.

BUT, when my wife got the wheels, the 8.5's look really front forward. I went on Summit and found the same wheels and they say it's the 5.25" offset PLUS 12.70mm offset.

Is this gonna work? Or do I have to return them and get these?

They're a 4.75" backspacing with 0.00mm offset.

Kinda bummed, but hoping for the best. I won't be there in person for a couple weeks.

Trucks a 69' C10 Fleetside, but looks like axles and whatnot are off a 72'. 5 lug axles, with discs up front.

Advice? Will the 20x8.5's work as is?

Thanks!
