Harbor freight has a decent engine lift adjuster
As said, go with the engine and trans assembled. It's easier to roll the car into it. I actually used to put a come along to the lift and roll them together. One man CBarge knows my work. I don't know part numbers and specs but I know how to put them together right
I strongly urge you get your paint work in the engine compartment done first.
Don't mind me. I post jumped. Been doing old mopars for 55 years. In my day, a quick swap was one day.
