I tried posting in an older thread about this topic but got no responses.

I am looking into installing an adjustable seat track. I don't like the idea of the small #14 self tapping screws into the 4" tube and wanted to know if anyone has tried installing the track with Rivnuts that accept 5/16"- 18 or 24 button head bolts with some locktite? Any other suggestions are greatly appreciated. Thanks!
