I pondered my issue over lunch and came up with a plan. A friend of mine who probably has worked on more TR6s than I've seen, happen to call me early this afternoon. His method is to use the pump (pulley) to hold the nut in place to start it a little -after the lock washer has been installed with the skill of a surgen. But my A/C bracket is in the way so much that I can't get anywhere near the one nut (see picture with my hand resting on the bracket, and my finger fully extended towards the nut, through the access hole in the bracket). So I got a piece of masking tape about 7" long, cut it lengthwise to the width if the nut, wrapped the nut in the tape like a spool of thread, and lowered it to the stud. Then using the water pump to guide the nut, I pulled the tape which spun the nut and got it started. It worked so well, I did the same thing on the other two nuts. Had all three started and tightened in minutes.
