You aren't dealing with torsion bars though. Granted most people it seems don't have much of an issue with the install outside the standard head aches.
I have to agree with the others that are wondering if the OP has the correct motor mounts.
To short of a mount would close the header/steering clearance and probably put the pipes in the wrong spot to clear the torsion bars.
For your sake i hope its a QC issue on their end and not something else.
