Meanwhile, MJG, i f it comes to yanking everything out, consider lightening your flywheel. I've heard a Packard maven report doing so to a 356. Wish i'd so done mine when for the sake of an effing $18 pilot bearing which squalling would wake the dead, we had to remove the transmission, so thought i'd replace the F-series Ford truck clutch so many 356 owners use, for a Packard pressure plate rebuilt using the original jig. As long as we were in the neighborhood. But, my flywheel's still stock weight. I bow to others' insight regarding this and don't want to give MJG a bum steer.
