I would do # 2
But to answer your question...undo the clutch adjuster nut on the clutch lincage that is between the z bar and the clutch fork.
Once you haveit loose enough you can un clip itfrm the Z bar andremoveit from the clutch fork. Then you will have to undo the Z bar ball studat the bell housingin orderto remove the z bar. once you have that removed you can then undo the u joints, and the tranny cross member, then the motor mounts, and the wiring, and then take it out thetop. You should take the rad out too.
I wouldn't take it out from the bottom. I think it would be more work.
You can either und the tranny from the Bell housing, or the bell housing from the engine. Either way would work if you are going to take the tranny out the bottom. butthefist one is easier I think.
Why do youwant to take it out the bottom? are you going to bendercoating the car? or doing a frame off resto? of not...take it out the top....way easier. remember to have the body secured to the hoist well. I had a buddie have his dart almost come off the back once he undid the last bolt on the K member. Oneperson can lift the front of a car without the engine/tranny/Kmember on it. really ligt.
