Hey guys. Been fiddling with electrical stuff, slowly getting things sorted out in the car. One of the big annoyances I have is the driver's seat. The previous owner was rather generously proportioned, so several of the springs in the driver's seat are broken. The pad doesn't sit properly in the seat (compared to the passenger seat) either, but I haven't taken the whole seat out yet, as I'd like to continue driving the car while waiting on my new seat/seat parts to arrive.

What are my options for replacing the lower spring bit in my 190D?
