Tighten than nut (a bit, not fully), screw the block in, make a note of how many degrees of rotational adjustment you need, take it apart, adjust. Repeat as necesary. Mark it to guard against unplanned movement during test fitting. There should be a "gripping washer" like a aggressive star washer, but bigger, between the threaded section and the actual block. Once you are certain on alignment, that threaded section can be threadlocked in place to the block.
I've got 2 that I'm restoring with the same issue...I'd heard of both methods.

I've just got to select the route of least risk.....however I've been tying to make up my mind for approx. 6 months.......( ;-)>
