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

thnx -we are planning to replace Z-bar, clutch adjustment rod, and TO and pilot bushing. I watched motor and trans lift slightly as he pushed down clutch pedal. Need to see bolts are tight I suppose. Noise thrashing/grind/dragging soind as you let up clutch pedal about half way engaged- fully up it goes away. especially notceable in revers but also in 1-2-sometimes 3. thnks for all comments

Does it make the noise with the clutch fully depressed and the transmission in gear and or in neutral? Which?

I found that spending a bit of time massaging the Z-bar and rod ends so they lie flat on the pivot points and are aligned in straight lines towards the opposite ends of the rods helped my linkage feel more efficient. I lube all contact points with CRC synthetic disc brake grease too. It won't wash out, has moly, PTFE(Teflon) and graphite mixed in a very high and low rated synthetic grease that won't attack plastic, rubber or nylon. It's an amazing lubricant.

They also sell a complete z-bar refreshing kit from Mopar that's available on-line at a lot of Mopar parts houses.
