We changed clutches for years by straddling the transmission with the floorboard removed, grabbing the shift lever, and manhandling the transmission in and out. Now I use a 4X4 post across the window openings and a cable come-along hooked into a short piece of chain bolted to a couple of the top cover bolts. If you remove the shifter, the transmission is a lot easier to handle. Just push down on the sheet metal cover over the shifter pivot with a big pair of channel lock pliers, push down firmly, and twist a little to the left. The cover will pop up from spring pressure under the shifter pivot.
