1972 jimmy need new clutch linkage sm465 hydraulic

Coming back from work yesterday my clutch linkage went out on me couldn't even get into neutral this part gave out . Anybody know where I can get replacement 350 with sm465 4x4 np205 hydraulic setup
This is another picture of my custom clutch rod lol the part with an arrow has a clamp that is supposed to tighten down and is adjustable but the teeth on the clamp are worn down and just spins when I push the clutch in and doesn't disengage clutch anymore what are you guys with conversion kits running for master cylinders and linkage

Re: 1972 jimmy need new clutch linkage sm465 hydraulic

Custom isn't the word I would use to describe that set up. I think Mac Gyvered is more appropriate. I can't speak for the hydraulics side of this system, but I can speak for the pedal assembly with the rotating lever arm. On a non-Mac Gyvered clutch pedal assembly, the lever arm is attached to the horizontal shaft with splines and a pinch bolt. Sounds like your splines are wiped out, or your pinch bolt is loose or non-existent. I'm assuming that the piece of channel iron is welded onto the stock lever arm, covering up the splined end of the shaft and pinch bolt.

I just ended up in welding the hell out of that joint on the bracket and made a new pushrod out of an eyebolt,carriage bolt and turnbuckle works 👍

Revisiting an old post but this whole hydro clutch setup is leaking now and feeling very spongy. Tried bleeding it but the same what are you guys running for hydro clutch conversion? I still have the SM465 stock clutch fork with 3 holes.

If I were looking to do this, I would use all mid-late 80's square body parts. I have an '85 C30 and an '86 K30 that both use hydraulic clutch setups on the SM465.
