Can someone help decode my trim tag? I'm not sure what the last set of numbers on the trim tag mean. I have also included the matching block numbers. Thanks! ST 70-13667 BL 00031 TR 755 48 B 9A 019760 030420 Engine: OL106660 and TO825CNJ

ST 70-13667 ~ 1970 Malibu Convertible trim level
BL ~ Van Nuys assembly plant
00031 ~ Data processing number for tracking purposes - block 8 of build sheet
TR 755 ~ interior trim code for Black Coated Fabric bench seat
48 B ~ paint color for Forest Green, B is for black vinyl top
9A ~ Assembly Date ~ September, 1st week
<------------ These are data processing tracking numbers for the car's build. Will match numbers in specific blocks of the build sheet but don't really designate any options.
019760 ~ Data processing numbers - block 24 of build sheet.
03 ~ Data processing number (SCHED. NO.) - block 10 of build sheet.
0420 ~ Data processing numbers - block 24 of build sheet.

0L106660 ~ partial VIN stamping identifying the year, plant, and sequence number of car engine was originally installed in. If you car's VIN is 136670L106660, this is the original engine.
T0825CNJ ~ Tonawanda engine plant, August 25 (0825) engine build date, CNJ is suffix code for 350-4bbl (300hp L48) with manual transmission.

Thank you for all the information! The block does match the vin! Do you happen to know if this is a rare combo for this model chevelle? How would I find out how many were made, because I have not found one all over the internet that has my options?

There are relatively accurate numbers for individual options such as the 350cid L48 at 85,212 units, but any number cited for combinations of options is only a WAG (wild a$$ guess) at best. No figures are known, that I'm aware of for interior or exterior colors. So when you see claims like, "Believed to be 1 of 20 blue convertibles known to exist with A/C and no power steering with a 350 3-speed" or such nonsense, it's just that, nonsense.
