This might help you:
My mounts were completely shot and thus, the engine was not where it was supposed to be, it seemed. So, when we tried to get those holes aligned, it was a serious 'no go' on one side. We pried, we pulled, we cursed; but only one side would line up (drivers).
Got in and bumped the motor by putting her in gear, No go.
So then I jumped behind the wheel and drove her down the hill and back. The hole got closer! Then I just drove the tar out of her for a few miles, and bingo, my friend managed to get that bolt started!
(Huge thanks to Charmalu for major help and support!)

Be careful, but you might consider taking her for a spin to 'settle' the motor in the right spot. Mind you, we had the driver side bolt in; and that is the most important side I assume, as those pesky oil cooler lines are right there, and if you don't have that side secured, you might be risking some serious issues bu burning through a line with your power steering belt.
