Looks like it...
Later serial numbers like 30784, 31577, 31929, 31784, 31652 (Chicago) and 31819 to Suburban Ford were never built
Final 2 weeks of "regular" production was all lower trim
I'd like to know the last 5 digits of the serial number...
I think the last (mid october) builds were all around 30XXX
I've found a few 31XXX ....but serials... generally do not match order built.
