wheel spacer question

Thread title said spacers, you're talking adapters.
First, I know of NO adapter from 5 on 4, to 5 on 5.5, or 5 on 5, for that matter. So I think the question is mute.
However! If you do find such hens teeth, make sure they are BILLET, and not cast garbage.
And yes, even if you DO find correct billet adapters, the chances of pickup truck wheels and tires fitting are slim, and none. And Slim has left town.
Sorry.
Edit: I have no problem at all with billet SPACERS, correctly designed and made. I use spacers on several cars, including fast ones.
2nd edit: proper adapters, IF you could find them, should probably be about $75/wheel.
Bottom line..... pass.
