I bought mine on JAN.8th had missing parts I was told that they would have to come from overseas.. I told them to order them but I built my own because what I built was heavier and better. Still have not received the parts 8 months later. Either send the whole thing back and get another one or build your own parts. I wound up building several of my own parts rather than use what was supplied.
What pieces that I used I reinforced them for more strength.
