Here's a link that I received from BIG BEAR over the weekendI don’t know if you have decided on engine mounts yet. But I wouldn’t recommend these http://www.jdjeeps.com/jdjeeps/mounts.ashx
I had them in mine and vibrated like crazy. I went with these for now

They took 85% of the annoying rattle/vibrating out of it, so far I’ve been happy although I don’t care for how much the engine can flex now. I may end up putting something like this in and see how it does.
