The simplest approach is to cove out the back of the backcheck at the point where the sostenuto would contact it. It doesn't take that long. If you know you will have the problem in advance you can shave more off the tails of the hammers if they aren't too heavily coved. Replace the backchecks with Renner checks which aren't as deep as the NY Steinway style. Finally (which you've already done) you can shave the pivot blocks slightly to move things distally a small amount. After the fact, coving the backcheck is the easiest.

Maybe someone else has found the easy way around this problem. 1917 Steinway M, complete action restoration, went just fine until I replaced the underlever assembly with a factory replacement. There is not enough room for the sostenuto rod between the backchecks and the damper tabs. I have even moved the entire underlever assembly distal about as far as it would go and it still is interfering. I am wondering if replacing the sos. rod with a late model rod will help? The original is one of the "cast" looking rods, and it appears to be larger than the modern ones. Anybody run into this and found a way through it?
