Lee,
It does on a GTE, not on a GZE, because that is where the supercharger fits ! No clearance problems that I found. You may need to lift the motor up to slide and then bolt the AC comp in there, but I doubt that.
Sounds like a worn steering box, may be time to rebuild / replace it.
The extra weight of a 1G will pull the front down lower on standard spec springs, be they TA22 or Corona, so I would keep an open mind about this.
Cheers,
Mitch.
