Let me start getting the tech out of the way. 1988 Turbo Coupe 351W carb with T5. Ride has been together and driving for quite some time. It loves clutch cables, broke plastic OE quadrant installed after market FMS I think. Broke that cable, next cable insanely hard to push after a week, a month I don't remember. Changed it, now new one hard to push. I have long tubes, I have wrapped the entire length of the under hood clutch cable with header wrap insulation on one of these installs no help. Put a small heat sheild at closest point from cable to headers, no help. Flywheel is from a 66-67 Mustang 289, with the clutch/pressure plate kit being a diaphragm replacement set for that application. Bellhousing and clutch fork were used items. I apologize because I know this is long and I have left something out but anyone have a suggestion?
