FWIW, the knob is threaded and I think when screwed in, it prevents movement of the rail that extends the seat. I think the threads might be 1/4 20, but I can pull it verify if you like. Have you looked in that general area to see if the previous owner just installed a 1/4 20 (or whatever size) bolt to keep it in place?
Thanks for the specs. I looked at it yesterday and there is nothing to hold the seat back - resulting in the movement. Since we don't need to recline the seat I'm going to screw in a bolt with a locking washer. Hopefully it's your recommendation 1/4-20 and not some special size. FYI I didn't see the rail or the bolt in the 280 parts list.
