Ok so I may have a little OCD but I'm missing 3 rubber pieces on the clutch pedal. The previous owner worn them right off. So could I put any other kind of rubber pieces that look like the original on?

 

same here, on all three pedals..

I don't care, honestly..

 

I am missing them on my gas pedal... i don't really mind, its more comfortable when I drive barefoot.

But you could definitely go to Home Depot and get some rubber door stoppers and put them there. Just a bit of gorilla glue or silicon and you are done.
