Replacements aren't cheap I found, so I managed to figure out how to put mine back together even with one of the stupid little plastic busings broken.
I had a ton of play in mine (the back housing actually moved) and found that the mount was actually broke where the housing fitis into it to hold stationary. I had to completely disassemble, take off the mount, flip it over and drill new mounting holes to fix the problem. Luckily the mount has a second notch on top that works to hold the housing.
