Dave,
Stock 77 911 does not have adjustable spring plates. Even with the adjustable plates, it would only make approximately a 3/4 max. height change. In order to achieve a 1.5 height change, you have to re-index your rear torsion bars. And could require multiple trials to get to your goal. The change in ride height to 1.5 is quite significant and the wheel alignment would definitely be affected. The final measurements should tell you what parameter/s need to be corrected/adjusted.
The camber will be most affected by this alteration. Toe-In to be determined. Having an adjustable spring plates would make your job much easier. Good luck.
