I am launching into a 2002 Spyder SMT gearbox rebuild/replacement. I have discovered the Road and Track business at Ipswich has closed. Is there still a source of locally rebuilt HPU and GSA units in Australia or do I have to go to  Monkey Wrench Raciing in the US?  We have the mechanical skills and equipment, but need a source of rebuilt parts.  
 
So far we don't know exactly what's wrong with it, might need some guidance soon.
