440/4 speed install, which method?

My 67 barracuda has had its engine out, for what feels like forever, and I'm almost at the stage to put it back in.
When I pulled it, I left the 4 speed in place.( with the fork left in there)
What's the best method for a reinstall.
1. Lower engine back in and stuff around lining the clutch etc back up.
2. Pull the 4 speed out, install the engine and then put the 4 speed back in.
3. Pull the 4 speed out and bolt it to the engine and drop the while assembly in from the top ( if that works?)
4. Drop the k frame etc and install it all from the bottom. ( I'm not keen on this idea)
Note: my car is a factory big block 67, so it has that massive k frame and the mounts are a ***** to line up. I'm thinking to remove the mounts, lower the engine in, get it nice and low to line the clutch up, slide it back, jack up the front of the engine, install the mounts and bolt her in.
Thoughts... Suggestions....
