Engine swap thread from He11

Ok so I am about to weeks from doing the engine swap from a /6 to a 360 in my 1973 Duster.

I have the

Engine
Trans
Tranny
Conversion Motor mounts
Trans line
Throttle Brackets
Radatior
Still need exaust

I know I will have to shorten the drive shaft not sure how much.
I am also going to clean paint and rewire the engine bay while the engine is out.

Can you guys think of anything I am missing this is my Daily Driver so I have to get the car back up as soon asap.
