I’m bidding on items to fix a model that I purchased. First I do not have a build sheet. This is why I have been continuing to search for parts. The need for a spare tire and F1/F2 was not discovered until I inventoried the model. If I would have known I needed so many different parts I would never have purchased the original F-40 model to begin with. I don’t understand your courier problem nor should I have to deal with it. If I could have forecast the need of so many parts this would never have happened. Sorry for your inconvenience, if a true problem let’s bring EBay in on the discussion and let them deal with your inconvenience?
