The Great Pumpkin - '71 Duster

At this point, how difficult would it be to install the engine from the underside with the headers/k-frame assembly?
I don't know but that was my original plan! I built a dolly that enabled me to take the engine and trans out as a unit so for all intents and purposes it should work to put it back in the same way (see post #303). The column, steering linkage and T bars would have to come out. That stuff is pretty easy to put back in so maybe?
