Dead Pedal For Free From Junk!
I just took the 10 disc holder from a broken CD player and put it in the corner to see how I would make one.
let my foot rest there a few times after stepping on the clutch, and guess what? It works.
Went inside and got some velcro with the adhesive back, stuck two strips on and jammed it in the corner.
It is black plastic, blends in with the black interior, and best of all it was free. Well free except for the $.28 of velcro.
look for junk around the house, something will fit. I bet a videotape would work too.
