Hi Aaron,
I'm with the other guys on not enough jack clearance causing the  
bobbling.  But in answer to your question about parts, give Schaff a  
call.  I know they aren't in the catalogue, BUT, when M&H had one of  
their clearing houses in the 80's, I believe it was Tuners Supply  
that bought up a bunch of their old parts.  Now that Schaff owns  
what's left of that,  there just could be some laying around  
somewhere, never know.  But unless the hammers are just flopping  
around from side to side, I really don't think that's the problem  
with bobbling.
