Matt,
I had the same issue with mine when i dropped the engine last month...
It seems the mount was previously repaired by "Hank" the crosseyed welder,and it was off by almost .250 top to bottom.
I had to cut it,remeasure and reweld it properly.Easy fix,just take the right measurements,tack it,remeasure and weld it properly !
Cheers !
Phil
