Motor mounts need replacing?

[Boneyard 79]

I just purchased a 79 CJ5 that is going to be a gift for my dad. I want to get it all "dialed in" over the winter so that it is ready to go in the spring. One of the first things I noticed was the difference in the driver side vs the passenger side rubber motor mounts. The drivers side looks much newer and more secure. There seems to be side-to-side excursion in the motor when I throttle the engine. I'm not sure how much is considered normal as I am new to this Jeep thing. Looking at the passenger side motor mount, the rubber looks worn, and I am concerned with increase in motion compared to the driver side.
My dad will be using the jeep recreationally (Limited to driving around town). Looking at the mounts, do you guys think I need to replace the passenger side mount? Is this setup safe?

I would replace them as they wear with time and are cheap. Also check the Transmission mount and torque stud to make sure they are OK. The torque stud helps keep the motor/tranny/Transfer Case combo from slapping from side to side.

stock mounts are pretty cheep, if you suspect they are bad and don't mind spending the time I would say go for it.

^^^^X2^^^^On all above info except the easy part.
Think about your Transmission mount too. Below is a thread from when I did mine.

Thanks for the information everyone. I'll just go ahead and replace the mounts. I'll have to check out the Transmission set up over the long weekend.
