I have a '69 Mustang which is getting a new clutch. As such, I also pulled the flywheel and had it resurfaced. I also bought new flywheel bolts. The old bolts had some sealant or threadlocker on the threads. I'm more inclined to believe that it's sealant because the bolts use star-type lockwashers and are torqued to 75-85 ft-lbs. A threadlocker might be overkill. Is there anything that is recommended by Ford for coating the threads on the flywheel bolts on this '69 302?
