'92 civic HB 5 spd - diff plastic blue bits on driver floor - half cylinder shape - 1"or 2.5 cm long.

Help needed please.

Found different blue plastic bits on driver floorboard.

These are cylindrically shaped pieces .... like a 1" (2.5 cm) long tube 1/2 inch diameter, cut in half longways

Clutch and brake switch **nylon rest pads** are already replaced 6 months ago so it should not be those.

besides these are clearly cylindrically shaped. No play or slop in pedals to give name a suspect.

Any ideas ?

TIA , for any help r.
