If you are using a hydraulic clutch setup with a chevy bellhousing Novak makes a pretty sweet setup that bolts to the outside of the bellhousing to hold the slave cylinder. Does away with the internal design. You could also find parts off of a mid 80's chevy, they used a hydraulic setup with external slave on the drivers side. My 86 dually 4x4 is that way. I put a nv4500 in it to replace the sm465 4 speed and used AA stuff. Bellhousing, clutch, slave bracket etc.
