156 Adjust seat angle
In the handbook for my 156 Sportwagon (my first Alfa, so please don't be too harsh if this is a dumb question!) it shows seat-angle adjustment wheels on the sides of the front seats, where the back meets the seat. But these adjusters don't exist on my seats. Instead in their places there are round plastic covers. When these are removed some kind of spindles are revealed but it is not clear what might be used to turn these, or what might be achieved by doing so. Is there any way of adjusting the seating angles using these? The passenger seat in particular is uncomfortably upright.
Thanks for any help.
