When I had my 35is, I changed a bank of 3 injectors. When my Indy took the three out and replaced them with the new ones, he returned one injector and told me that one didn't need replacing as it was the same index 12 as the replacements and it looked OK.
If anyone needs or wants a single injector (No guarantees obviously if it is OK), PM me and you can have if free except for postage.
