I am missing the seat that fits on top of the spring and below the ball on the gear shift lever. The drawing in the Master Parts Catalog (1929-1948) page 188, shows the piece (4.027 SEAT). I can not tell from that if it is somewhat cone shaped and concave on the inside and convex on the outside. I may have found the part I need, but the vendors photos appear to show it to be shaped more like a brass thick washer. He does not know if the part is correct either.

Anyone have any photos of Group Number 4.027, part number 590868?

Thanks
