Those 17's will likely rub. That's a lot of backspacing, intended for later-model trucks. I think 4.5-ish B.S. is about all you can do without hitting tie rod ends on the older Chevys. If you're stuck on 17's, try the 84-8880 instead. Same wheel but with a 1/2-inch less BS. (17x8, 8 on 6.5", 4.5 BS)

The 16's will fit fine. And the tires will be cheaper, too.
