Couple of things, first DON'T take the tilt knobs, or the center plastic cover of knobs off. An easier way, just take the rod with knob attached, and pull out after you have removed the chrome cover next to the center transmission tunnel. You can also release the chrome cover at the knob, but you can not take off until you have released the "C" rings on the rod, inside the seat. First you have to take off the back board of the seat, it will slide down once the two screws that hold on the bottom of back board are un-screwed. Once you have the back board off the seat, you will see the "C" rings (2). Just take out, slide the wheels off as the rod is being pulled out. Note, that the tilt gear will slide out of the spring loaded teeth. Make sure you release the small spring holding these teeth. It really is very easy to do. I have heard too many horror stories about taking the tilt knobs of the rods. Also I don't think MB knobs are still available, some after market might be.
Now next, I would use the "hoarshair" for your pads, they feel so much like the new feel of the Pagoda, and they are firm, and they have always been made of a natural plant/tree fiber. They are not of a horse's hair, and is spelled hoars. It is just a term used. The new pads are sprayed with rubberized coating to hold the materal together better. I think this is the way to go. Now I have been told that the pads are NLA from MB. You might want to check. I ordered pads for a friend on mine a couple of years ago from GAHH. Those pads are being made in Mexico by the supplier for VW. I also understand that these are no longer available. You will want to check.
