WTB: Model Y Comfort Suspension Springs

Looking for a set of Model Y comfort suspension springs to pair with my Tein dampers. I really only want the rears for now, but I’d also buy the fronts if the deal was right. Part numbers listed for the fronts are for the entire strut assemblies, but I’m really interested in just the springs if willing to separate, else we can maybe work something else out.

Willing to cover shipping.

Part numbers:
Rear: 1188474-00-C
Front left: 1188363-00-H
Front right: 1188368-00-H
