I could really use some help right about now.

If you loosen both of the motor mounts from under the car, you should be able to shift the engine a bit and it may give you some more room. If that doesn't do it, get one of the mounts from a late 70s Dodge Truck.

I'm not suggesting this brand, I'm just showing it as a picture. If you go this route, it will lift the engine some under the hood, so you may have clearance issues. You really shouldn't need this mount, though. The stock stuff should fit if they're in good shape, and the engine isn't shifted to the side.

It's hard to tell from that pocture, but that mount looks like it might be turned 90 degrees from correct.
