Motor Mounts Problems - Putting in a 78 350

[Blue_Aura]

So I was putting in the 78 4 Bolt Main, 2 piece rear seal, 350 and things are just not going well. The front motor mount does not match up at all. The previous 350 was a 68. Is the front motor mount different on a 78?

Also, I got the passenger mount lined up and a bolt in it, but the Driver's side is just a tad off, and I just cant get it to line up. I have two bolts in the bell housing on each side. It seems like the Driver's side needs to go back just a hair, but I can't get it to go back enough. I have checked and rechecked, and have tried jacking up the Turbo 350 to see if it will slide back some.

So, my major questions are:

1. Do I need a different front motor mount for a 78 350?
2. Any ideas about getting the Driver's side to line up enough to get a bolt in it?

Any help is much appreciated. Thanks ahead of time!!
