Here are several more options for removing an SM420 or SM465 from a truck. Remove the shifter and tunnel hump. Remove a couple of bolts from the tranny cover and replace with longer bolts(?) and a short length of chain. Now you can run an engine hoist in thru the door and lift the tranny out. I found a problem with the lifting arm on the hoist being right up against the heater vent above the hump. I used two bolts that were diagonal from to back. You could use two back cover bolts, but this would leave the front heavy on the chain. To get around the tranny not being balanced on the chain and help with installation, make up a couple of guide pins by cutting the heads off some long bolts. Then thread the guide pins into the top two tranny mounting bolt holes.
Another method is to use a piece of wood(s) shoved thru the windows and a short come-along, or a ratchet hoist. I haven't done this yet, I intend to the next time. For the wood I'd use either two lengths of 2x4 'T' together with screws, or a piece of 4x6. I'm not sure 2x4 by itself would hold the tranny.
