Really Broken motor mount !!! HELP!

Uh, well, i learned that one of the mounts was broken on the 6-bolt i pulled out of the VR4. Namely the front one, and i don't mean broken as in, unbolt it and put another one on, i mean the block broke off where the mount is connected. Can i JB weld or attach those pieces that broke off to the block again? or should i use the n/t block that was in the GGSX i have. thanks!

You could try and fix it, but it might just be easier to use the other block.
