This is likely a long shot... The white plastic pieces that toggle inside the seat control switch have broken on one of my switches. These switches can be taken apart but it does not look like anyone sell parts for them any where, you can just buy a whole new switch. I am trying to avoid buying a new switch since these are repairable. So, I am hoping that someone might have some old weeded out 964 seat and would be willing to part with a switch or someone has broken switch that broke some other way and would be willing to sell some pieces. I will pay for parts and shipping to southern California. I am looking for the piece standring up in the picture with the round hole in the center. This is for the 4-way switch. Thanks
