One thing I forgot to mention, I would recommend removing the clutch delay valve. It is a little plastic orifice that restricts flow of hydraulic fluid to the slave cylinder. I found that on high RPM shifts it was difficult to shift, often resulting in missing a gear due to it just not wanting to go in. After I removed this from the line, it was night and day difference. No more problems. Good luck on getting your window sticker. I still have mine!
