-- Solved (kinda) ----
So after allot of confusions and looking about and even emailing Haynes with an email title wrong information, I've found:
Some model 306's do not have resistor blocks. Instead attached to the heater blower motor there is a section that regulates the power.
I have attached a photo - item 2 is the resistor block.
anyway going to a scrap yard to find one hopefully.
cheers for the help
