Loosen up the engine and transmission mounts and see if shifting the motor around a bit helps, then lock everything back down. There's usually some wiggle room. I have the factory-replacement style milodon in my car, last time I R&R'd the engine, the link was touching the bottom of the pan's rear surface afterwards....before, it at least had a small amount (like 1/4"-3/8" small!) of clearance. I also noticed the header had previously been close enough to the pass. side fenderwell that it left a small rubbed spot(it wasn't touching at rest, but must have been too close with the engine and body moving during driving). Jockeyed it around and got clearance everywhere it was needed..
