Product review (4 stars): It worked as designed.
It worked as designed.  It is much easier to install if you view one of the instructional videos available on the 'net.  In my case, the housing has an extra tab (or retaining ear) just to the right of the pin which prevents it from moving to the right and falling out.  So I do not have, or need, a tinnerman on the left side.  Do not break this extra tab off or you will need to order the tinnerman and delay your repair while waiting for it.
