Sorry, not trying to hijack but I am looking for these parts as well That push nut washer you circled in blue, I am missing both of those. I dont see them sold anywhere. Im thinking this and the large washer are something I can source at a local industrial supply house. Also, Those 4 round pucks in the upper left of you pic, after some research it appears they are spacers that go under the seat slider/riser? Mine did not have these. I wondered why the stud was so long underneath the car, Lol. I dont see these sold either.
I can make these if it comes to it, but it would be great to find a place to buy all of this and be done with it. Do these spacers go above the carpet? That sounds like a dumb question I know, but the spacers seem overly large and unsightly, that's why I ask. Any input is helpful. Thanks!
