Use a C-clamp with blocks of wood and an inverted short bolt whose head fits on the pin.
Monitor the FP as you turn in small increments. Not much movement is needed to affect the FP.

I have my doubts that using a C clamp on it's own can achieve the small changes required as for me I would find it nearly impossible to know if the pin has moved at all and by how much, but monitoring the fuel pressure while performing is a very good suggestion that overcomes this.
The 81 911 has hard lines but the wur to distributor line has a flexible section and can be moved easily. The wur return line moves around too but maybe not enough? Maybe I'll try it out next time.
