Novak Conversions Jeep Wrangler TJ engine mounts

Has anyone replaced body mounts and not broken bolts?

10 mount bolts came right out, the center front was very tight and squeeked most of the way out. I was able to PB blast the top side through a small crack into the void on the radiator support. The end of the bolt was wet when it came out, so it may have helped a bit, but I still needed a 1/2" breaker bar.

Anti-seize, when you put them back in.
