Tuning pins more longs

[afinador]

I make restorations of piano in Belo Horizonte MG - Brazil. To five years 
that we have used only the Denro mark for tuning pins. I am ahead of a 
problem: He is in the phase of re-stringing old uprigth Bechstein. This 
model is not very common in Brazil therefore its pinblock is closed (for the 
iron plate) and does not possess bushings in tuning pins. The plate of iron 
in pinblock has 7mm of thickness and tuning pins that I removed of there had 
75mm of length.  Then. No American or German suppliment company who knows 
offers tuning pins longers today (6/0 or 7/0 x 2-3/4).  Will not be possible 
to substitute pinblock for a budgetary question (and nor she would advance). 
 I promise a statue in the door of our workshop who to help me to find 
tuning pins 6/0 or 7/0 longer than 2-1/2.  Much thankful
