A messy job getting the pan bolts out, and you'll need to rotate the crank just right to pull the pan, but no need to undo motor mounts or steering links. Figure on about 4 hours+ depending how hard it is to pull out the old rope packing. We had to use some small brass rod to displace the old packing as it disintegrated on the corkscrew. Used it like a punch as it wrapped around the crank / upper seal groove, then pulled it back out. You may want to make a "puller" for the brg cap out of 1" angle iron to jack it out of the block. Drill it to roughly match the oil pan bolt holes, use a stack of washers between the block & angle iron to position it off the block, then use two pan bolts into the brg cap to pull it out of the block. Repeat the process with longer block bolts and more washers as needed.
Good luck!
