16x10 wheels fit on a 1971 K-10

[johnmix2]

I have a 1971 K-10 4x4 1/2 ton 6 lug with disc brakes. I am installing a 4" lift kit and I am looking at a set of 16x10 wheels with 4.5" backspacing. Will these wheels fit without rubbing on any of the drivetrain components? Wheel outlets only show 15" wheels available for this year (I suspect because that is factory specs.) LMC has 16x10 6 lug wheels for sale but notes that they will not fit 4wd.

Anyone running 16s? will they fit without issues? Thanks.
