pickeyeater334's ebay clutch stop.
There's a
thread here about it. To install it just put the nut on the bolt, then replace your existing plastic clutch stop with this one. To adjust: turn your key in the ignition, then press the clutch and listen for a relay to click. You want your clutch stop adjusted to just past the relay click point.
Easy and inexpensive mod and makes shifts easier and more predictable.
