73 Challenger Approximate Build Date Assistance.

[73Challengr]

Trying to get an approximate production date for my 73 Rallye. Unfortunately no fender tag or broadcast sheet.

The Vin ends in B364769 that would be Hamtramck plant....Sequence Number: 364769  =  264769th Vehicle Built

Being the 264769th, i'd guess late in the year but I thought i'd ask to see if anyone who knows their date has a sequence number near mine. Thanks y'all!
