Hi. I have a hydraulic set up on my 240 chevy for several years and it works great. The clutch master is a 7/8ths bore unit from Tilton. It fits in the stock location with very little modification of the body. The pedal is a V6 unit from Volvo that you can still get. The push rod is a clevis I found at a hardware store and a rod that I made. The one tricky part is the preasure line. There is very little clearance between the end of the master and the strut tower. I used a stainless hose from a hydrolic shop with a banjo style fitting. I used a sealing washer on either side of the joint with a hollow bolt and it worked just fine with just enough clearance. The slave is not there as I used hydrolic throwout bearing, but thats another story.
