[TR] tr3 carpet clips

[Frank Fisher]

on TS41366L December 1958, i have some carpet clips that are screwed to the
firewall.
each side gets 2 clips.
each clip is about 1 1/2" wide.
they are
manufactured from spring steel.
imagine a piece of 0.02" thin steel bent over
at 180 degrees. one edge is cut to have 2 sharp teeth and the teeth  are
further bent 90 degrees.
when screwed to the firewall the open end faces down.
one brings the carpet up and pulls open the spring (nicking one finger), then
you tuck the end of the carpet into the clip and when you release the clip the
teeth clamp onto the carpet holding it in place.
neither of my friends 1957 or
1962 have theses.
are they factory?
is any one making replacements?
thanks
Frank
