Late model wheels on my 69 c-10

[Pont406]

My coworker bought some bling bling wheels for his late model chevy. Old wheels and tires have 2000 miles on them. He wants $300 for a set. I am sure that he will take $250. I took one wheel home to see if I will like it or not. Bolt pattern is fine but the hub is too big. Also, rear wheel will not clear. I can probablly get some wheel adapters but that will add $100 or so. What do you guys think should I pass or buy them? Thanks
