A833 - Identification and HELP!!

Per Brewer's Performance page:

Beginning with the 1968 model year (July 1, 1967), the main case has a small (3" by 7/8") raised, machined rectangular pad on the passenger side of the transmission, just above the casting number. Along with the vehicle's serial number stamped onto it, this pad will have a second line beginning with "PP833" followed by a 4-digit (10,000 day calendar) date code, such as "2264" (10-9-67) or "3055" (12-08-69) and sequential assembly number (405) for that day (pictured).
