At first I thought they were too long and wanted to return them. I filled out the return information and wanted to measure the old nuts to see what length I need. When I pulled out the old nut, it was the same length. I had a hand thread and it caught on the nostril. I plugged it into an outlet and it worked fine. It took a little more finger strength to move it past the point where it was floating. Everything else went well. Too bad I don't know which van the originals drove with the bump, wrong size head and rounded 24 nuts. At least I know the store and will speak to the manager. If you need a different set these are the ones for the Tacoma PreRunner 05.
