Engine/Tranny Installation from Under Car – Instructions Needed

Guys,

1970 Challenger

Any good links of videos/instructions on how to install engine/trans from under car like factory. I don't have a lift, so need instructions on:
- Dollies for engine and trans to assemble, then roll under car.
- Best way to lift front safely
- All the mounting bolts/locations. Tips of what other infrastructure should be installed before installing engine/trans.

Other option is to remove hood and drop it in, but any advice on either method is appreciated.

Thanks!
