Ok, back to it...

Spring perches are the same for all pickups. SRW axle is the narrowest of all three, cab and chassis DRW axle is about 3_4" wider, pickup DRW axle is about 3-4" wider than that.

Like I said if you have a cc axle, I've run them srw the rear tires come out and fill the wheel well, looks ok to me.
All 8 lug are 8*6.5 though dually do use 5/8" studs vs 1/2" for most srw.
