I had a set of spacers on a Mustang years ago and they kept coming loose, no matter what I did. But my Sons tell me wheel spacers are very common and stay on in the bagged S10 community. Maybe they have improved them from the cast ones I had 40 years ago.

There are also spacers where the original axle bolts pass through them and into the wheels, the spacer then acts as only a spacer, not an adapter. You have to install 3 inch long wheel studs, like the drag cars use, but those will not come loose. They are billet and have several bolt patterns drilled into them.
