Greetings, 
 
          Is it a bad idea to replace dampers on an old upright with ones that are longer, we're talking about 3/8" longer (3/16ths at each end). ...and this would be for the bass's bi and mono dampers only. Is the longer length going to cause a problem when the damper goes to lift? 
 
Also, while I am in there, is it a good idea to verrrry slightly (bend) each damper's spring wire so that it strengthens their pressure on the strings? Is there a way, perhaps a gage, to measure the pressure of these springs? If it can be measured, what should it be?
 
Thanks
