I can’t get the cab onto the chassis. The drivers hands are blocking the steering wheel. The wheel need to go under his hands but there is not enough wiggle room to sort this.
Somebody else must have worked this out. It’s a bit crowded in there as there is an MFC in the sleeper and the speaker is hot glued to the roof of the sleeper
The only thing I can think of is to take the glass out of the driver door, pop the steering wheel off, and once assembled, glue the steering wheel back on through the window
