Before taking the SLS to bits, drain the resivoir , clean it well and refill with new fluid and filter ~ the system is often full of old burned up fluid you don't want in it after you've taken the leveling valve apart and rebuilt it .

M-B still sold the kit last thing I knew .

Depending on where you're located a matching good used seat cover *might* be a junkyard item.....

We took three W126 seats apart to mix 'n match and get one really nice one for my brother's W126, he's still raving about the improved support and comfort, no pool noodles needed although I plan to install them on my W123 driver's seat in addition to the non broekn spring box .
