Having a good fit is important

5/5

These have been on my 1975 Pontiac Firebird for a while now and they haven't slipped at all. will not fit a During the replacement of the rocker studs, I discovered that the new studs were threaded differently. The long and the short of it. Anyway, you can be sure these will work beautifully in whatever you're using them for. The quality is excellent.
