Boss 335 Wheels fitment?

[shenk10]

I'm looking into getting the boss motorsports 335 wheels. Looking at getting 20 x 8.5. The backspacing is 5.671 in. I know people had problems with the Boss 338 wheel fitment and they were suppose to be coming out with a new wheel to fit out trucks, but I was wondering if anyone put the 335 on their truck or if anyone knows if they will fit our trucks. I have an '82 c10 2wd, 5x5 lug pattern if that matters. Thanks for any help.
