Undated Supercedes


Recommended Posts

While reviewing @zed2's thread on unchained vs. chained gas caps I spotted @26th-Z's comment about undated supercedes on that item. I recalled seeing a similar catalog notation on door lock assemblies while recently doing research for a friend. Today I was cleaning up some door lock assemblies and spotted a unicorn the probably confirms the timing of this particular supercede (80501-E4100, undated supercede 80503-E4100). The lock on the left is a left side unit, date coded 9 - 7, it has two clock-style coil springs, Note the position of the long arm is down on the smaller spring. The unit on the right is also a left side unit, date coded 9 - 11. It has only one clock-style spring with a different shape and positioning. The other major change is the elimination of the clock-style spring for the primary latch in favor of a tubular coil spring. This type spring is on all later dated units I have. Differences in the pin stamps can be seen in the second pic. Another difference I spotted: internal bumpers for the various levers were clear plastic on the early unit, black plastic or rubber on the later units. Unfortunately I have only the one 9 - 7 unit, no matching right side.
