The addition of the plastic upper bearing is causing me a bit of concern. In my case, the bearing interferes with rivets placed through 6F10-2 (the original CH601-HD upper bearing) and 6F8-2 (firewall stiffener). These parts can be sen on page 11 of this document: http://www.zenithair.com/pdf-doc/601-firewall-gear-rib.pdf I am using UHDMW (or some such mix of letters) 3/8" thick. I cut notches to clear the rivets. What is bugging me is that I could not find any comments about this interference, so maybe I am doing something incredibly wrong (I am not content with doing anything just "credibly" wrong). My "notched" upper bearing can be seen here: http://www.flickr.com/photos/54366879@N06/7359287022/ These notches might be weakening the part to a point where it will easily brake and be ineffective, reason why I am planning on a duplicate (no notches) installed on top of it. Comments, anyone?
