I have a later truck ('66) so I don't know if pulling an engine is the same for mine as yours but... When I pulled the engine from my donor truck it was attached to a 3 speed overdrive trans. I left them together and they came out without a problem. My truck has a 4 speed in it, and I decided to go with that instead of the 3 speed. Shortly after I put the engine in my clutch went out, so the engine had to come back out. With the 4 speed, I had to pull the engine seperate. Then I pulled the trans out because I was having problems getting the engine to mate to the trans with the other clutch. But to get the 4 speed out I had to pull the shifter, then unbolt the bellhousing from the trans. The bellhousing then came out easy, and the trans came back and out under the truck. I had a permanent crossmember in the way of the whole thing coming out it one piece...
as far as what to take off, I think having the whole front clip off is the easiest. Hope you get it figured out, good luck.
