Which way to swap? Separate motor and gearbox in place or pull together?

Yep ! You can tilt it as you pull it then level it off as needed to clear the header panel . Just pulled my engine last week .
Generally I drop it from the bottom but this time I am installing a 46rh and will need the K-member to position the new trany in order to figure out where I need to cut the floor pan .
