Yep, Front wings/running boards off, rear wings can stay on! cowl/grill first. Rest really depends on what you are doing but Id also remove the gear box and transmission covers first as well. Ed's video is very good but the body can stick to the chassis by way of the rubber isolating strips so when applying lift to the body be prepared to ease/help the separation, If the engine and g/box have been removed its possible to lift the chassis whilst undertaking a body lift and watch it drop dramatically. This release tends to allow the body to move and as you will see your lifting points are not fantastic to start with! You'll need a two post lift minimum really as you can then store the body in the lift footprint and reposition the rolling chassis where you want it!. Stripped out two can lift the chassis and position it on tressles out of the way but you really do need space and its not a job to be rushed. Also expect to find much more work to do than you may have expected!

Good luck with the planned work, the Morgan doesn't really have any horrible surprises to throw at you as most of it's construction is old school logic but it just takes time, more than generally planned for!
