Son and I built a 727 with TF-2 kit. New bushing in the tailshaft with a booted seal. New slip yoke (Strange).

A leak developed that would leave a small puddle while parked. Replaced the seal with a non-booted version and fabbed a heat shield for an X-pipe exhaust crossover below the area for some extra protection. Would still drip a few drops after sitting. (BB Dodge D100 truck. Exhaust dumps in front of rear wheels so x-pipe is farther forward than it normally might be).

Son moved the truck recently to a different spot and later found a Valdez size puddle - again below the tailshaft seal. (Guessing that the converter drained back).

Any suggestions? Thinking of pulling the tailshaft and installing another bushing and booted seal.
