1969 Barracuda 340 Formula S Restoration

There is a thin metal spiral seal ring at the top. If it is trashed (rusted out) out then the pivots are junk.
Doing the upgrade like said and cleaning + new grease will save the pivots if the top ring is ok. The tube full of grease helps keep the water from running in with the new gasket kit and obviously lubricates the pivot action.

If the top ring is gone or rusted out it is a waste of time.JMO!

like said Nice work on these!
