YC Grand Action Height

As I replaced the old brackets I noticed like Bob said, the new brackets were about 3/32's shorter in height. This was needed......Originally, while removing this action "both ends" hammer flange screws had scraped the underside of the pinblock. I almost wondered if it would come out without damage! 

NOW...after the new brackets, setting the action spread to 112.5 mm and a bench regulation I attempted to slide the action back into the piano. A few regulation screws in the center of the action will not clear the bottom of the stretcher board.  

The clearance between the two is at best, very close but the stretcher board upon measurement is about 1/8 inch lower in the center of the piano. The ends hammer flange screws are clearing now on the ends but not by much. Guess enough that they are not the problem.

I am reluctant to reduce the dimensions of anything more than what may be absolutely necessary to clear for future servicing and not alter the actions calculations. I just feel that the action needs a little more space to clear safely.

Your suggestions ... muchly appreciated!
