68 390 in a 60' thunderbird

Hi, I've got a 60' t-bird that has a 64' 390, as the original 352 went bad after only four years. I got a pretty good deal on a rebuilt 68 390 long block (casting # C8AE-C) and I wanted to know if the motor mounts differ from a 64' engine to a 68'. If they do is there a full size ford mount that will allow me to put this later FE in my early bird.

Thanks for the help,
Erik
