22 in wheel fit

[Afterlife72]

I want to put 22x9.5 in back and 20x8 Boss 338, and after a Nationwide shortage on these wheels have foun the 22's but backspace is 5.79 inches the wheels have a +14 offset. Will these fit the back of my 86 shortbed with a 4/6 drop?

That should be the perfect offset for the room back there. I wouldn't go wider than a 305 tire tho. My 315s barely fit with the same offset on an 8" wheel.
Post pics for sure.
