    Does anyone know of a kit to install a hydraulic clutch on a 72 K5 4x4 with an sm465 4speed? My legs are killing me in traffic, but I don't want to give up the standard tranny.

    Nice, thanks Cal, I had this same question. Getting sick of my clutch linkage failing when it gets a little twisty!

    My solution would be to dump whatever clutch you have and go with a Centerforce II before trying to go with a hydraulic setup. The Centerforce II with modified mechanical linkage in my Blazer takes less pedal effort to funciton than the hydraulic clutch in my Fiero (Centerforce I setup) does. It also has better pedal feel and is smoother than the hydraulic setup in my Fiero.

    Anyhow, nobody I know of makes a kit, but I remember that Ken Brown had a hyurdaulic setup on his '72 Blazer that used a Fiero clutch master. I don't recall what slave he used, but I think that later he went to a late-model GM bellhousing with an internal hydraulic throwout setup (because he has an NV4500). I cna't find Ken any more, so I don't know much else I can tell you.

    I used a wilwood master cylinder and a McLeod hydraulic throwout bearing...I haven't used it yet because I'm still in the buildup phase but I expect it to work very well.

    1970 GMC Jimmy 502HO/SM465/NP205 doesn't run just yet!

    Steve, You said to use a CenterForce II clutch. Do you know what the numbers are for the clutch? I went to the Center Force web site and they didn't list one for a blazer.

    I replaced all the nylon bushings in my Z-Bar, welded the wear spots in the clutch pedal to z-bar rod and ground them smooth, then replaced the adjusting rod with a Heim joint and threaded rod and my clutch is way better than before. It's much smoother and easier to push. I've gotten pretty twisty in my truck and my clutch linkage has never failed. Are your motor mounts and cab mounts in good shape?

    Never said I could spell!
