Hi everyone. I just got the 9395 tow truck and on the 14th page of the manual it tells me that I need (among others) two numbered parts, 4 and 6. I looked really hard but only found numbered 3, 5 and 6. Could this be a mistake, or am I just that stupid and can't find the right part?
Note: I am absolutely new to technic. This is my first set.
