I have a clutchnet 1x PP (dual diaphram) in a d16a1 in an 86 crx...don't ask :P
Anyway, the pedal is crazy hard and I keep on stripping the plastic threaded adjuster on the clutch cables about every month. I got a metal threaded one once, but it's dead now because the other ends gave out on me.

Does anyone know where to purchase one or a supplier of the metal ones?
My dealer only supplies plastic threaded ones.
TIA
I can take pics if you don't know what I am talking about.
