X2. Paint them flat black and they look just like a stock mount. Been doing this for years
to keep the clutch linkage from going to far out of alignment. Works great.
It does transmit a little more vibration thru the chassis. But having a predictable
clutch pedal was always worth the trade off for me.
Used with a stock rubber mount on the right and poly trans mount keeps things from moving around too much no matter how mean you wish treat it.
