Motor mounts replacement instructions needed

Hello, I have question to ask. I have the truck listed above. Today while I was getting the pickup ready to change out the Pittman arm and idle arm, I found out that the “motor mounts were shot”. If possible, could you tell me step-by-step how to change out the motor mounts? I was told by a friend that you have to jack up the motor to change out the motor mounts. I looked up under the pickup this morning, I didn’t see a place to jack the motor up. I noticed that you can’t jack the motor up from the front of the engine because there is a big metal plate that come up from under the engine (welder to the frame of the pickup) and it cover the area under the crankshaft and belt puller. “Need help real bad”. Thank you, Bill H.
