TTI Header install issues

I can't recall ever installing any set of headers on any Mopar where you didn't have to disconnect a bunch of stuff and also lift the engine off the mounts for the install. I think TTI does a good job with instructions... what do they tell you to do? Production tolerances on these cars are all over the place, so shimming one and/or both motor mounts might be necessary. You may also have to get rid of the factory steering coupler and replace it with a Borgeson or Flaming River U-joint.
