boss 338 wheels 5x4.74 with adapters fitting?

[jacobfour]

I came across boss 338 20" wheels with new tires $700, but they are 5x4.75 bolt pattern but they were on a 95 Chevy with 5x5 1" adapters. I've read about a bunch of fitting issues with these wheels. I would think with the adapters they should be fine since most had to run some kind of spacers anyways to get them to fit even if they r the right bolt pattern. I have no drop on my 68 long bed c10 with 5 lug conversion. Never ran adapters those so idk do they hold the wheel on good or am I going to be tightening lug nuts every trip i take? will they even fit? am i going to have a wheel fall off ? is having the wheels stick out 1" going to make it look like a gangster nacho rig. bc I don't want that it looks like there's plenty of room in the wheel wells and u wouldn't notice them sticking out 1"?

Any help would be appreciative.
