Hardware question

[bob888]

The screw called out for the seatbelt attach point in the cabin top is NAS517-5-9. These are too short (I have a headliner). I need NAS517-5-12 but can't find a source (unless ordering 100 or more). Anyone had to find longer screws for this problem? Where?

I'm having a hard time visualizing this, but I think you want the shoulder belt anchor up against the cabin top, not suspended below a headliner. So the standard length screw should work.

http://www.gen-aircraft-hardware.com/ has them in packs of 10.

Even with the Aerosport headliner, I was able to use the stock seat belt attach bolts. The headliner kit even comes with a thin spacer to hold the seat belt bracket flush with the headliner (not crushing it).
