Clips to go on "nail heads" inside transmission tunnel?

[Addicted]

My TR7 has three "nail head" looking things inside the tunnel that held plastic clips.  The clips are all broken, and I haven't succeeded in finding a replacement.  Two clips on the passenger side hold the rear brake line and the fuel tank vent line.  One on the driver side seems to have held the speedo cable.  

Are they available somewhere?  Are there good alternatives to attach to those "nail heads"?  

I could post a picture, but I'm embarrassed with my ratty looking underbody.  LOL.

Here's what it looks like.  It literally looks like a framing nail that didn't get sunk all the way.  That clip you show may actually work.  Perhaps a little dremel work.
