OK, so here's the deal: This is not a mind-free automatic screw things in, take the check and run operation.
This is a good lesson in all the alignments that must be optimal for the action to function.
The key frame must be bedded. Observe alignment of hammers to strings, knuckles to rep levers, jack to knuckle core, wippens to capstans, hammer tails to back checks.
Don't assume things were done that carefully in the factory, and who knows what was changed to cope with the expanding brackets?
If 12 hammers are perfectly aligned to the strings and 76 are off to the treble side, is there something you can do to shift the rail to bring 76 in alignment? Then what happens to the rep lever/knuckle alignment? Etc.!
If you don't know how to think of all these at once, this job will teach you!
Very satisfying to optimize basic action functions.

Subject: Can't get action out
Whippen rail screw holes might need to be ( a ground them out with a dremel tool ) expanded in order to line up with the new brackets' threaded screw holes.

To insure the top action rails stay in the same location, replace the end brackets first.
