W108 seat spring assembly

The driver's seat in my 1973 280SE 4.5 w108 has an annoying sag dead center. The pads have been replaced, but that didn't solve the problem. So I assume some of the springs are worn out or broken.

However, I can't find a source of supply for the spring assembly (haven't had a response from an email to the Classics Center).

Short of a parts car, where do I find or how do I replace the springs?

I checked into this as well. Best bets are a parts car with good seat springs or get a spring set made. Some ownersw have placed swimming noodles alongside the springs to give extra tension to the sagging springs.

Easy job to fix/overcome, without buying a new seat. This is also a good time to check for degraded seat pad and replace as necessary.

Remove the seat from the car (4 bolts, 15-20 minutes). Compress the seat (have someone sit on it), and remove the skins. Take note on how they are fastened to the seat frame.

If you do in fact have broken springs, they can be re-welded at a local shop for next to nothing. If it's the seat pad, that can be replaced in no time flat (if the seat pad is toast, you'll see dried crunchy things in the floor boards).

To remove the seat, take off the skins, replace a pad and put the reassembled thing back into the car will take about 2 hours (it took me more, as I was a novice )
