Hi Avery,
You have two choices. The first is to reduce the width of the cheek block, 
which will also mean relocating either the dowel, or the hole in the 
keybed, as well as that for the screw. The second is to reduce the width of 
the bass stop block (?) and re-align all the hammers. You might have to 
shave down where the shift lever ear engages the action, and the clearance 
channel for sliding it in. The third of your two options is to whittle away 
some keyframe and hope you can get enough shift before C-8 hits the cheek 
block. I'd go for door number 2. It's least destructive, easy to dance to, 
most likely to work, and sits most lightly on the conscience, if not the 
schedule.

It's a hand built piano, after all. Just needs some more hand building.
