Changing engine mounts

[Duster Flyer]

I need to change the engine mounts on my Starduster, IO540 dynafocal.
Last time I did this, getting everything to line up was a BXXXX! Therefore I must assume I was doing something wrong. Anyone have a method that worked for them? Bolt type and torque information will be useful too. Thanks in advance,
Willie Spence
