The bearing assembly that comes with it is the hydraulic throw-out style with the hydraulic tubes already assembled and ready to install. It still requires a 3/4 clutch master cylinder and the fabrication to install it to the pedal. Weirs kit seems to simplify the fabrication of the lines and the majority of the pneudraulic issues to an acceptable level for installation and hookup. It appears to be well made and rather simple to assemble. I just bought the LS1 T56 for $600 and with this kit I am still at the $1200 mark. Granted, I still have to get it drilled out for a speedometer cable, but all in all I think I'll come in under $1800 to get it in. Mike KZ was a big help and when I found out about the Weir product, I shot him an email about it. The guy I bought it from did not research the product well enough. He could have used it on his other car but he didn't know about the conversion package and I surely wasn't going to enlighten him. Thanks for all of the tips; I do appreciate them
