1972 jimmy need new clutch linkage sm465 hydraulic

[gmc1971harwich]

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
