    New or used...?I would say like less than $100 if you get them used or from a yard...But I would seriously consider getting new stuff, at least as far as the master cylinder, slave cylinder, and hose are concerned...

    New the parts are not too bad either...

    MC ~$60 from GMpartsdirect
    Slave Cyl. ~$60 from GM parts direct
    Hose ~15 from GMparts direct
    Shift fork ~20 from GM parts direct

    I have the PN's as well for most of the stuff if you need them... I think MJ has the PN for the new clutch pedal...

    ok i did a search and am still not clear on something's (because i think the threads i read were people converting to a manual trans) do i need a new bell housing, pedals? or do i just mainly need the stuff that fortcollinsram listed above or basically just all the part #'s M J posted everything ill need? Thanks for the pictures i saved those along time ago knowing i would be doing this someday /forums/images/icons/grin.gif

    sorry if this dosen't make much sense

    the list I used pretty much covered what I could buy at the chev dealer at the time.
    I would go junkyard shopping if I were to do it again.
    that was pre internet for me and I didnt have a clue if it could be done.

    hydro clutch was probably the greatest driveability improvement I have made.
    I was hoping it would make my wife more inclined to drive it, now it has firebird bucketseats with extremely long tracks(85 mustang sourced) to ensure she can feel confident to reach all the controls.
    now she can concentrate on the lack of visibility with no other excuses

    If you get the Hydro Pedals, there are support pins which help when lining up the master cylinder. When this is all lined up, it pretty much bolts together.

    If you don't get the hydro pedals, lining up the master cylinder can be difficult. My friend and I did this on his '72 (obviously different pedal racks). The master was off ~1/2 inch side to side. We had to make a "spacer" on the pedal rack. It was also off up and down and forward and backward ~1/2" we ended up welding a "tab" onto his pedal to bring the mount backward more into the cab, drill a NEW hole as well as a little higher. This STILL isn't quite right. There is some binding within the Master Clutch. I am worried this binding will lead to a pre-mature failure on the master Cyl.

    Lining this all up is critical to easy clutch operation.

    We both have CFII clutch kits. He has an 11" disc on a 402. I have the 12" disc on my 383.

    Mine is quite a bit easier to use than his.

    Check out my pics below.

    Good luck.
