    C2 diff. build date vs. car build date

    Hello! I have a 1966 with an approx. mid January build date. It is a St. Louis body dated 1st week of that month (don't know if that is relevant). What would be an accepted date range for the differential for this car?
    Thanks for your time!

        Steve, if you have Nolands book, take a look at the pages where he matches VIN to ratio to build date. Map it out. As an example in 63, the 3.36 rear was installed on many cars. I determined that I needed a rear that was built about 10 days prior to the car build date.

        The other ratios in 63 were a lot more than 10 days.

        NCRS is 6 months, but as mentioned, close to the car build date is better.

          Recently traded up on my new/old 67. Bought a 67 Lyndale blue L-79 Coupe from second owner of 24yrs. I know all nos. match, broach marks etc. The build was March 1 67. The engine pad VO220HT Casting date B/3/7 Trans M-21 Build P7B20, Differential is AO 1 7 67 (Jan. 7th 67) So Diff. is within 2 mos. Oh yeah this cars Vin is 12346, Buildt right behind Roy Braatz's Vin.12345 L-79 with 427 Hood. As doce'd in Noland Adams Book. Guess what my has Org. Laquer Paint and The 427 Big Block Hood. Let the sparks fly. It is what it is. Probaly need to Judge it. But I know these nos. are org. and our diff. is within 6-8 weeks for reference.
