Smokin deal, if they fit?

[aitch]

I asked before, but the thread was so stretched out if may have been hard to follow.

Tire and wheel package:
Front: Boyds 17 X 8 (back space 5") with Yokohama AVS-ST 265/60/17
Rear: Boyds 17 X 9 1/2 (back space 5 3/4") with Yokohama AVS-ST 275/60/17

My truck; 69 3/4 GMC LWB. I'm putting 2 1/2 drop spindles on front and 4 inch drop coils on rear. Will add 71 1/2 ton disc saddle and trailing arm 12 bolt rear.

Tires and wheels have 5-8 thousand miles on them. I looked at them today.
If they fit, they're mine for a great price. I need help!!

Thank you
