That big white ring looks like what is at the bottom of my '66 automatic column shift. Then, over the top of that is the piece gtx6970 has a photo of in this thread. The ridge around that white piece goes into a molded edge that fits over the seal in gtx6970's
No, I ordered a new one of these seals and it fit over the bottom support just fine. I am just not remembering where those little plastic rings came from. They are sized to slide over the steering column shaft somewhere. Sized just like the little bearing at the top by the "bucket"...but there doesn't seem to be room up there. By the time I get the snap rings, bearing and insulator, blinker assembly, and the two metal plates that go on each side of the plastic blinker assembly, there doesn't seem to be room up top. If I try to put them up on the steering column between the steering wheel and the blinker assembly, they would get crushed.
