Yes I can post them tomorrow with good light if it helps with a real suggestion to the problem. The wall I don't believe is vertical as I got front and back vertical when it is put at an angle to the right but then the sides are way out which meant it had to be brought back to get these which throws the upstand out. I have a good solid fixing in the chimney but when the pole is mounted in the brackets it don't mount flush between them as the chimney wall is not horizontal either which I believe causes the movement. It works ok but beyond 30e 30w the problems occur.
Mentioned this elsewhere but you appear to want to try do it with a method that does not will not work. Mount has to be plumb only been very slightly out can be corrected your way on one plane.
I would remove your T & K brackets from the wall.
Then with a file every bolt hole will need to be elongated to allow further adjustment which at the moment you can not get due to running out of adjustment on the ubolt slots.
Id have that pole plub in all directions in under an hour, you are looking at this all wrong.
