I know someone who has used the method that TimD described, so it must do some good. I've used a Mityvac (vacuum bleeder) myself, but it takes two steps for me because the clutch hose on a 1500 makes an arch that goes higher than the master cylinder, so there's an air pocket that collects there no matter what you do. Once the slave is bled, I've just pushed hard on the clutch pedal several times (haven't needed the plastic over the cap), and bled the slave again. The air pocket in the translucent clutch hose is gone after I've pushed the pedal hard a few times. I've never figured out whether that air pocket gets displaced to the slave, or if it gets sucked back down to the master when you release the pedal. Anyway, my $0.02 on clutch bleeding, and yes, it seems to be a pain no matter which vintage of Spridget you have.
