What year is your truck? Just curious because that was a major consideration for me when fitting tires/wheels. Not sure if you know, but the 67-early 70 housings are narrower than the late 70-72 housings. If someone converted your truck to discs/5 lug they might have used the narrow housing but if it's a factory 5 lug it would be wider. If the wheels are $500 each, the axle housing/5 lug swap would probably be cheaper. But if wheels are less than $150 like mine, then obviously that's the way to go.

But to make my wheel/tire combo fit the wider axle was the only choice based on the backspacing available on the wheels I was willing to $$$.
