'68 Barracuda 383 4spd - throw-out bearing/other issues?

OK so it has wrong z-bar which makes it too short to line up with a straight rod off the clutch fork, hence the s-shaped rod - also the bracket with pivot point on trans is a home made affair that does not look like it lines up perfectly with linkage. I saw engine and trans actually lift up on their mounts when clutch is operated.. Starting point seems to be getting right linkage and then go with new TO and pilot bushing. Comments /suggestions appreciated. Anyone been down similar road?
