Option 1) replace with 1974 Clutch master, braided SS flex line, July 1974 slave, and 11” low diaphragm LUK Clutch. This combo has been working for 27 years on the first clutch.

Option 2) stock Slave and master. Custom centrel force clutch from @FJ40Jim and call it a done with it.

I've been running the mid to later 70's clutch master and slave for decades with my sbc's. Follow the stk 40's adjustments in the fsm. Set you pedal height and adjust accordingly.

I have the luk clutch. I’m not sure what year the slave is. I’m going to try adjusts the pedal or rod actuating the master cylinder. If it drags on too long I’ll order the 84 master and slave. I ordered the braided line today.

I’ve been beaten into submission and given up on the center force clutch. I’ve ordered the mid to late 70’s clutch master and slave. Have the stainless line and the 11” luk flat diaphragm clutch. Now which length release bearing do I use. I have 2 lengths. I’m using the Chevy cast fork and a stock GM cast bell housing iif that makes a difference.
